	* [r1776] NEWS, ChangeLog, dist/config.sys, dist/mkbindist
	  Last minute fix for 1.4.0: fix #1713278 COMSPEC setting wrong.
	  Use config.sys/autoexec.bat distributed from here in the bindist
	  instead of the one in dosemu-freedos-*-bin*.

	* [r1775] NEWS, ChangeLog:
	  Release 1.4.0.

	* [r1774] INSTALL, README, README.bindist, doc/README.txt,
	  doc/announce, src/base/init/install.c, src/doc/README/config,
	  src/doc/README/header:
	  More documentation updates; added a quick more basic introduction at
	  the beginning of README.txt.

2007-05-04  Bart

	* [r1773] VERSION, doc/DANG.txt, doc/README-tech.txt, doc/README.txt,
	  doc/announce, doc/dosemu-HOWTO.txt, etc/dosemu.conf,
	  src/doc/DANG/DANG.sgml, src/doc/HOWTO/dosemu-HOWTO.sgml,

	  src/doc/README/config, src/doc/README/port-io,
	  src/doc/README/recover, src/doc/README/runasuser:
	  Documentation updates for 1.4.0.

	* [r1772] src/dosext/mfs/lfn.c, src/emu-i386/simx86/codegen-sim.c,
	  src/plugin/commands/lredir.c:
	  gcc-2.95 compatibility fixes.

	* [r1771] src/base/init/config.c, src/emu-i386/ports.c:
	  Convert error about direct port i/o without root into a warning.
	  Err about using "-s" without enough privileges.

	* [r1770] src/arch/linux/Makefile.main:
	  Fix man page out-of-tree building.

	* [r1769]  (almost all files changed)
	  Update copyright line to 2007.

	* [r1768] dosemu.spec.in:
	  Added missing new directory and symbolic link to dosemu.spec.

	* [r1767] src/arch/linux/Makefile.main:
	  Make man files at "make" instead of "make install" time.

	* [r1766] dist/dosemu, dist/dosemu.bindist, dist/mkbindist,
	  man/dosemu.bin.1.in, src/arch/linux/Makefile.main,
	  src/base/init/config.c, src/base/init/install.c,
	  src/base/init/parser.y.in, src/base/misc/fatfs.c:
	  Allow --Flibdir for suid configurations, as it hasn't been used to
	  locate global.conf for years. Document the allowance for
	  --Flibdir/--Fimagedir. Repair bindist/mkbindist to work with the 
	  new FreeDOS configuration. This means using --Flibdir and
	  $DOSEMU_LIB_DIR instead of the hardcode DOSEMULIB_DEFAULT.
	  Run mkfontdir at "make" instead of "make install" time when possible.

	* [r1765] src/plugin/commands/lredir.c:
	  Fix lredir c: d:

2007-05-03  Bart

	* [r1764] configure, configure.ac, src/plugin/sdl/Makefile:
	  Fix forgotten make distclean file in SDL plugin; add -lXext for
	  Xxf86vm checking on certain systems.

	* [r1763] INSTALL, configure, configure.ac:
	  Check for the existence of the Xxf86vm and Xext libraries, not just
	  header files. Adjust INSTALL instructions.

	* [r1762] config.guess, config.sub, configure, configure.ac:
	  Don't use -mtune by default. It doesn't bear much relation to 'uname
	  -m' anymore on anything newer than a Pentium Pro.

	* [r1761] etc/dosemu.users.example, src/base/init/config.c,
	  src/base/init/parser.y.in, src/base/misc/priv.c, src/include/priv.h:
	  Register the difference between sudo and suid-root.
	  Use c_all as the default for users who run dosemu via sudo so
	  dosemu.users does not need to be edited for that case, leaving
	  the default "restricted" (only console graphics at the console,
	  no remote direct hardware access) setting for suid-root.

2007-05-02  Bart

	* [r1760] src/arch/linux/Makefile.main:
	  Use -rm instead of rm to deal with non-existing directories.
	  Use bdftopcf at make time instead of make install.
	  Fixes problems reported at linux-msdos (perry hargrave).

	* [r1759] src/base/init/parser.y.in:
	  Repair $_sound=(on). You would only get the old sound driver via
	  $_sound=(1).

2007-05-01  Bart

	* [r1758] src/env/video/dualmon.c, src/env/video/hgc.c,
	  src/env/video/matrox.c, src/env/video/vc.c:
	  Mark all mapped video memory PROT_EXEC, similar to the VGAEMU memory.
	  Solves a few problems with console video on x86-64.

	* [r1757] src/emu-i386/simx86/fp87-x86.c:
	  Use aliased memory for emulation of FSTENV/FSAVE.

	* [r1756] src/emu-i386/simx86/cpatch.c:
	  There is a slight chance that the CPUEMU cpatch stubs hit VGA memory.
	  For that case there is a simple instruction decoder but we must use
	  explicit assembly instructions. Fixes another problem with Norton
	  SysInfo.

2007-04-30  Bart

	* [r1755] src/emu-i386/simx86/codegen-sim.c:
	  Fix regression in vgaemu handling from #1754.
	  Fix problem with rep movs with df set backwards for simulated cpuemu
	  with planar VGA modes.

	* [r1754] src/emu-i386/simx86/codegen-sim.c,
	  src/emu-i386/simx86/sigsegv.c, src/env/video/vgaemu.c:

	  write to ROM in CPUEMU, such as Norton SysInfo.

2007-04-29  Bart

	* [r1753] src/dosext/mfs/mfs.c:
	  Check for FAT filesystem before attempting to use the VFAT ioctls.
	  Also check if the first entry is ".\0" to avoid an ioctl32 bug in
	  kernels <= 2.6.21.1.

2007-04-27  Bart

	* [r1751] VERSION, NEWS, ChangeLog, doc/DOSEMU-HOWTO.txt,
	  etc/dosemu.conf:
	  Regenerate documentation. Release 1.3.5.

	* [r1750] src/plugin/commands/lredir.c, src/plugin/commands/msetenv.c:
	  Avoid CPUEMU problems with msetenv. Only set DOSEMU_LASTREDIR if no
	  drive letter was given; improve lredir command line processing with C
	  and R.

	* [r1749] etc/dosemu.conf, src/base/dev/misc/lpt.c:
	  Flush every second when printing. Fix $_lptx="" to not register any
	  ports.

	* [r1748] src/dosext/dpmi/msdos.c:
	  Fix #1638135 (int 21h, ax=6300 not translated currently, japheth)

	* [r1747] src/dosext/mfs/mfs.c, src/dosext/mfs/mfs.h:
	  Always return . and .. as the first two entries for
	  findfirst/findnext to be consistent with real DOS. On Linux they
	  can be somewhere in the middle.

2007-04-26  Bart

	* [r1744] man/dosemu.1.in:
	  [ 1692149 ] Describe --version in man page (fix for 1245033) (Stuart
	  Axon)

	* [r1743] src/doc/HOWTO/dosemu-HOWTO.sgml:
	  Some HOWTO updates by Stuart Axon (#1692299).

	* [r1742] src/emu-i386/simx86/codegen-sim.c,
	  src/emu-i386/simx86/codegen-x86.c, src/emu-i386/simx86/codegen.h,
	  src/emu-i386/simx86/cpatch.c, src/emu-i386/simx86/interp.c,

	  src/dosext/dpmi/dpmi.h, src/emu-i386/cpu.c, src/include/cpu.h,
	  src/include/emu.h:
	  Use fxsave/fxrstor when available on i386 to deal with SSE fp.
	  Make sure the fxsave buffer is paragraph aligned (fixes a bug with
	  DJGPP gcc on x86_64).

2007-04-22  Bart

	* [r1740] src/dosext/dpmi/dpmi.c:
	  Check fs/gs values before loading them on x86-64. Preserves 64 bit
	  segment bases on Intel chips (but apparently makes no difference on
	  AMD's).

2007-04-20  Bart

	* [r1739] src/dosext/dpmi/dpmi.c:
	  Fix LFB w/console graphics for x86-64.

	* [r1738] src/base/async/pci_bios.c, src/base/dev/misc/pci.c,

	  #1436788.

	* [r1736] src/plugin/term/keyb_slang.c,
	  src/plugin/translate/charsets/utf8.c:
	  Fix problems with utf-8 multibyte input in terminals (reported by
	  Grigory Batalov, linux-msdos).

2007-03-29  Bart

	* [r1735] dist/dosemu, src/base/init/config.c:

2007-03-11  Bart

	* [r1726] src/emu-i386/simx86/cpu-emu.c, src/emu-i386/simx86/interp.c:
	  Use leavedos(1) for EMU86 failure to drop into dosdebug; improve
	  diagnostics. For rep outs, use not_permitted and let the port code
	  deal with it instead of quitting DOSEMU.

	* [r1725] src/emu-i386/simx86/cpatch.c, src/emu-i386/simx86/trees.c:
	  Break node if current eip is in a page to be unprotected; fixes bug
	  #1678581

2007-03-10  Bart

	* [r1724] src/dosext/mfs/dosc.c, src/dosext/mfs/lfn.c:

	  Merged trivial changes and makefile improvements from Stas' new midid
	  code.

	* [r1715] src/arch/linux/Makefile.main:
	  Do not erase all previous FreeDOS files when upgrading. Remove risky
	  comment between semicolons.

2006-11-22  Bart

	* [r1714] src/plugin/sdl/keyb_SDL.c:
	  Fix AltGr handling with SDL. It was confused with ScrollLock.

	* [r1713] src/plugin/sdl/keyb_SDL.c:

	  Added CDROM lredir documentation. Regenerate documentation.
	  Release 1.3.4.

	* [r1709] src/arch/linux/async/debug.c, src/base/init/lexer.l.in,
	  src/base/misc/fatfs_boot.S, src/base/misc/utilities.c,

	  adjust README.

2006-11-16  Bart

	* [r1707] src/emu-i386/simx86/sigsegv.c:
	  Fixed some 64-bit rip usage, and the division by zero exception.

	* [r1706] configure, configure.ac, src/include/config.h.in,
	  src/include/dlmalloc.h:
	  Fixed gcc warning in dlmalloc and removed some obsolete autoconf
	  macros.

2006-11-15  Bart

	* [r1705] src/arch/linux/Makefile.main:
	  Rearranged the messages after make install, so it is more clear
	  that the FreeDOS tarball is missing.

	* [r1704] src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/interp.c, src/emu-i386/simx86/modrm-gen.c,
	  src/emu-i386/simx86/protmode.c, src/emu-i386/simx86/protmode.h,

	  Segment handling and address calculation optimizations for
	  cpuemu.

2006-11-14  Bart

2006-11-13  Bart

	* [r1700] ChangeLog, NEWS:
	  Updated NEWS and ChangeLog

2006-11-12  Bart

	* [r1699] COPYING.DOSEMU, src/env/video/vgafonts.c:
	  Added VGA font and dlmalloc copyrights for completeness.

	* [r1698] dist/autoemu.bat, dist/autoexec.bat, dist/config.emu,
	  dist/config.sys, src/arch/linux/Makefile.main,
	  src/base/init/install.c, src/base/misc/fatfs.c:
	  The previous approach had circular symbolic links for directories
	  which is bad as it confuses DOS programs. It seems clearer to
	  create a drive_z directory with contents equal to the old freedos
	  directory (even though there may not be a freedos present).

	* [r1697] dist/dosemu, src/base/init/config.c,
	  src/base/init/install.c, src/emu.c, src/include/dos2linux.h,
	  src/include/emu.h, src/plugin/commands/unix.c:
	  Create no-prompt initial boot for DOSEMU+FreeDOS with a welcome
	  screen. The liability disclaimer just needs to be confirmed.
	  Removed the win4lin check from the dosemu script and moved the
	  terminal instructions to the main code.

	* [r1696] dist/autoemu.bat, dist/autoexec.bat, dist/config.emu,
	  dist/config.sys, dosemu.spec.in, src/arch/linux/Makefile.main,
	  src/base/init/install.c, src/base/misc/fatfs.c:
	  Remove the tarballs with symlinks. Instead, point d: to the
	  systemwide FreeDOS directory during config.sys processing and use
	  z: after that. Install config.sys et al from dosemu.

	* [r1695] etc/dosemu.conf, etc/global.conf,
	  src/base/dev/misc/lpt.c, src/base/init/lexer.l.in,
	  src/base/init/parser.y.in:
	  Use $_lpt1, $_lpt2, and $_lpt3 for printer configuration and
	  disable the printer IRQ for now since it's not used. Fixes
	  #1492201.

	* [r1694] src/base/async/int.c, src/base/bios/setup.c,
	  src/include/int.h:
	  Fix missing LFN support after ctrl-alt-del (#1487899)

	* [r1693] INSTALL, compiletime-settings,
	  compiletime-settings.devel, compiletime-settings.help, configure,
	  configure.ac, default-configure, src/emu.c,
	  src/plugin/sdl/acinclude.m4, src/plugin/sdl/configure,
	  src/plugin/sdl/configure.ac:
	  Use JIT cpuemu by default on x86-64, and don't force -m32 any
	  longer. Introduce target_bits compile time option to optionally
	  set -m32 or -m64. Updated SDL configure script and added a link
	  check for cross-compilation.

2006-11-11  Bart

	* [r1692] dist/dosemu:
	  Use `id -ur` instead of $UID for dash compatibility.

	* [r1691] src/arch/linux/async/signal.c, src/dosext/dpmi/dpmi.c,
	  src/emu-i386/cpu.c, src/include/cpu-emu.h:
	  Fix compilation with cpuemu off.

	  src/emu-i386/simx86/sigsegv.c, src/env/video/instremu.c,
	  src/env/video/vgaemu.c, src/include/vgaemu.h:
	  Implemented better VGAEMU support for simulated cpuemu and
	  eliminated the e_vga_base and e_vga_end variables.

	* [r1689] src/arch/linux/async/signal.c,
	  src/emu-i386/simx86/cpu-emu.c, src/emu.c, src/env/video/vc.c,
	  src/include/emu.h, src/plugin/term/terminal.c:
	  Handle all async signals except those that call leavedos using
	  sigasync() which calls the correct sighandler using a function
	  pointer array. The real signal handlers are all set in
	  signal.c:signal_init() now. Add SIGWINCH & SIGPROF to the queue
	  block list because of their nature.

	* [r1688] src/emu-i386/simx86/sigsegv.c,
	  src/emu-i386/simx86/trees.c:
	  Fixed some issues with self-modifying code.

	  src/emu-i386/simx86/tables.c, src/emu-i386/simx86/trees.c:
	  Removed GenBufSize hack and adjusted the op size array.

	* [r1686] src/emu-i386/simx86/interp.c, src/env/video/instremu.c,
	  src/include/cpu.h:
	  Avoid "lahf" (may not be available on x86-64) and use READ_BYTE
	  for IS_IRET.

	  src/emu-i386/simx86/cpu-emu.c, src/emu-i386/simx86/interp.c,
	  src/emu-i386/simx86/trees.c:
	  Fixed a bug in InvalidateSingleNode and DPMI TheCPU.eflags
	  handling. Under normal circumstances IOPL should never be set
	  there.

	* [r1684] configure, configure.ac:
	  Add -lm to LIBS as DOSEMU now uses a few math functions.

	* [r1683] src/emu-i386/simx86/fp87-sim.c:
	  Fixed rounding to integer in the FPU simulator.

	* [r1682] src/emu-i386/simx86/codegen-x86.c:
	  Fix das/aas/aam for x86-64.

	  the QEMU i386 emulator test program.

2006-11-09  Bart

	* [r1680] src/emu-i386/simx86/interp.c:
	  Correct ofsseg array for DPMI

2006-11-08  Bart

	* [r1679] src/emu.c, src/include/emu.h:
	  Forgotten sigjmp_buf declarations from r1677.

	* [r1678] src/plugin/sdl/sdl.c:
	  Enable X background pause for SDL

	* [r1677] src/base/misc/utilities.c, src/emu.c:
	  Use sigsetjmp/siglongjmp because signal handlers may be involved
	  in leavedos.

	* [r1676] src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/sigsegv.c:
	  Fix BSF and BSR, and don't use code patches for DPMI code for
	  cpuemu="full". Fixes Duke Nukem 3D in this mode.

	* [r1675] src/emu-i386/simx86/interp.c:
	  Use the operand size instead of the address size for jump
	  destination masking. Fixes some issues with cpuemu in DPMI.

	* [r1674] src/emu-i386/simx86/codegen-x86.c:

	  src/emu-i386/simx86/codegen-x86.c, src/emu-i386/simx86/interp.c:
	  Use load/op/store for inc&dec, and optimize inc/dec byte reg.

	* [r1671] src/emu-i386/simx86/codegen-sim.c,
	  src/emu-i386/simx86/codegen-x86.c, src/emu-i386/simx86/interp.c:
	  Use load/op/store for xchg and actually use xchg in generated
	  code as well.

	* [r1670] src/emu-i386/simx86/codegen-sim.c,
	  src/emu-i386/simx86/codegen-x86.c, src/emu-i386/simx86/interp.c:

	  src/emu-i386/simx86/interp.c:
	  Use "op %al,reg" style instructions in cpuemu instead of "op
	  (%edi),%al" to avoid certain VGA memory reads.

	* [r1668] src/base/misc/dump.c, src/dosext/dpmi/dpmi.c:
	  Fixed a DPMI ctrl-c problem (missed in_dpmi_dos_int), and avoid
	  dumping unreachable memory in dump.c, which may double-fault.

2006-11-06  Bart

	* [r1667] src/dosext/dpmi/memory.c:
	  Save actual dpmi base pointer in config.dpmi_base.

	* [r1666] src/emu-i386/simx86/cpu-emu.c,
	  src/emu-i386/simx86/fp87-x86.c:
	  Changed fp87 absolute addresses to bx-relative so that the FPU
	  works for x86-64 for JIT cpuemu, and improve x86-64 cpuemu fault
	  handling.

	* [r1665] src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/trees.c:
	  Fixed VGA read/write for x86-64. Misc adjustments to deal with
	  64-bit pointers. Add forgotten #include.

2006-11-05  Bart

	* [r1664] src/base/misc/Makefile, src/base/misc/dlmalloc.c,
	  src/base/misc/smalloc.c, src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/memory.c, src/emu-i386/simx86/trees.c,
	  src/include/dlmalloc.h, src/include/smalloc.h:
	  Use Doug Lea's malloc (forced to use mmap with PROT_EXEC) instead
	  of smalloc for cpuemu. It is a lot faster.

	* [r1663] src/base/misc/smalloc.c, src/emu-i386/simx86/memory.c,
	  src/include/smalloc.h:
	  Introduce smalloc_fast and smfree_fast: these clobber the
	  allocated memory to improve the speed of smfree (eliminating a
	  linear search). Used by cpuemu: shaves ~25% off DOS boot time.

	* [r1662] src/base/misc/smalloc.c, src/include/smalloc.h:
	  Changed smalloc to use a double-linked list for a little
	  performance improvement.

	* [r1661] src/emu-i386/simx86/codegen-sim.c,
	  src/emu-i386/simx86/cpu-emu.c, src/emu-i386/simx86/trees.c,

	  src/emu-i386/simx86/trees.c, src/emu-i386/simx86/trees.h:
	  Clean up pointer casts in cpuemu tree handling. Use int instead
	  of long where possible/appropriate.

2006-11-04  Bart

	* [r1657] src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/codegen-x86.h, src/emu-i386/simx86/codegen.h,

	  src/emu-i386/simx86/syncpu.h, src/emu-i386/simx86/trees.c:
	  Implemented stack/write code patches for x86-64 and fixed an
	  associated bug in trees.c.

	* [r1656] src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/codegen.h, src/emu-i386/simx86/cpatch.c,

	  src/emu-i386/simx86/sigsegv.c, src/emu-i386/simx86/syncpu.h:
	  Reorganised the SynCPU structure and rep stos/movs code patches
	  to use call (%ebx), and enable those on x86-64.

	  src/emu-i386/simx86/emu86.h:
	  Cleaned up cpuemu eflags handling. DF is now always handled via
	  TheCPU.eflags instead of the stack flag image, and always clear
	  between instructions. Disabled the pushf VIF trick which doesn't
	  seem to work as advertised.

	* [r1654] src/emu-i386/simx86/interp.c:
	  Correct cpuemu regression from rev #1652

2006-11-01  Bart

	* [r1653] src/emu-i386/simx86/codegen-sim.c:
	  Correct flag handling in AAA, AAS, DAS, DAA, CMPS*, SCAS* in the
	  cpuemu interpreter. Fixes problems with FD DEBUG's "a" command.

	* [r1652] src/emu-i386/simx86/cpu-emu.c,
	  src/emu-i386/simx86/interp.c:
	  Fix single stepping in cpu-emu (including dosdebug).

2006-10-31  Bart

	* [r1651] src/env/video/render.c, src/env/video/text.c,
	  src/include/render.h, src/plugin/X/X.c,
	  src/plugin/sdl/mouse_SDL.c, src/plugin/sdl/sdl.c:
	  Fix palette and mouse with SDL for fbdev/fullscreen/256 colors.

	* [r1650] (almost all files changed)
	  Update year to 2006. COPYING now contains the pure GPL, and
	  COPYING.DOSEMU the other copyright details. Distribute the GPL
	  and COPYING.DOSEMU with rpm's from dosemu.spec. Clarified the
	  clause on redistribution of repackaged official packages.

	* [r1649] src/plugin/X/X.c, src/plugin/sdl/sdl.c:
	  Don't call SDL_UpdateRects with 0 rectangles: it may crash. Fix
	  the close (x) window button in xdosemu.

2006-10-30  Bart

	* [r1648] src/env/video/text.c, src/plugin/X/X.c, src/plugin/X/X.h,
	  src/plugin/X/X_font.c, src/plugin/sdl/sdl.c:
	  Don't call X functions directly from SDL code, that won't work
	  with SDL libraries that are not directly linked with X. Added
	  more checks for x11.window availability. Fixed mouse/input focus
	  cursor blinking situation.

	* [r1647] src/plugin/sdl/sdl.c:
	  Initialize most of the X support before creating the first window
	  (except for window and font), where it was done previously.
	  Avoids some issues with dynamic loading.

	* [r1646] src/plugin/X/X_font.c:
	  Fix crash in SDL if X_font = "" (thanks Reinhard).

2006-10-29  Bart

	* [r1645] src/env/video/text.c, src/include/vgatext.h,
	  src/plugin/X/X.c, src/plugin/X/X_font.c, src/plugin/sdl/sdl.c:
	  Add X font support to the SDL plugin. There's a bit of a trick
	  involved (a second "Display") to receive all expose events. Did
	  some associated cleanup.

	* [r1644] src/plugin/X/Makefile, src/plugin/X/X.c,
	  src/plugin/X/X.h, src/plugin/X/X_font.c:
	  Moved X font handling into a seperate file with seperate static
	  variables, so X fonts can be used by SDL later.

	* [r1643] dist/dosemu:
	  Replace bash-isms in dosemu script with sh constructs.

	* [r1642] src/env/video/text.c, src/plugin/X/X.c:
	  Introduce a new Window in the X code, drawwindow, that is a
	  subwindow of either the fullscreen or the normal window, so can
	  be reparented (technique borrowed from SDL). The main advantage
	  is that the X server can take care of shift_x/shift_y for text
	  modes. Also no need to copy gc's any more. Fix crash for a too
	  eager update_cursor().

2006-10-28  Bart

	* [r1641] src/env/video/render.c, src/env/video/text.c,
	  src/include/render.h, src/include/vgatext.h, src/plugin/X/X.c,
	  src/plugin/sdl/sdl.c:
	  Create a "bitmap" text system in render.c that is shared by X and
	  SDL. Implemented line drawing (for mono underline) on the canvas.
	  The text cursor and underlining now go through the remapper on X.
	  Remove scaling from the previously used X calls (impossible with
	  X fonts). Screen updates now lock the surface during the whole
	  update for SDL; the SDL code pushes rectangles to be updated and
	  sends them in one go. Mode changes need to be checked before
	  locking the surface: moved the mode adjust calls out of the
	  common update code.

	* [r1640] src/arch/linux/async/signal.c, src/env/video/text.c,
	  src/include/vgatext.h, src/plugin/X/X.c, src/plugin/sdl/sdl.c,
	  src/plugin/term/terminal.c:
	  Remove update function in text_system struct. The only user was X
	  with XFlush but XFlush is not necessary if XPending is called
	  often enough. Moved event handler call in signal.c after update
	  calls to be sure of that. Similarly the mouse cursor update is
	  best placed before other updates.

	* [r1639] src/env/video/seqemu.c, src/env/video/text.c,
	  src/env/video/vesa.c, src/include/vgatext.h, src/plugin/X/X.c,
	  src/plugin/sdl/sdl.c, src/plugin/term/terminal.c:
	  Remove X_resize_text_screen from text_system structure. Resizes
	  are done on demand by update_screen(); set vga.reconfig.re_init
	  to be sure of that in all cases.

	* [r1638] src/emu-i386/simx86/codegen-sim.c:
	  Correct DAA & DAS in simulator.

	* [r1637] src/emu-i386/simx86/codegen-x86.c:
	  Implement AAD and AAM replacements for x86-64.

	* [r1636] src/emu-i386/simx86/codegen-x86.c:
	  Implement JIT code for AAA,AAS,DAA, and DAS for x86-64 as they
	  are not available in long mode. Fixes FreeDOS debug which uses
	  DAA, in particular.

2006-10-26  Bart

	* [r1635] src/base/init/parser.y.in,
	  src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/codegen-x86.h, src/emu-i386/simx86/codegen.h,
	  src/emu-i386/simx86/cpu-emu.c, src/emu.c, src/include/cpu-emu.h:
	  Enable dynamic code generation for x86-64. Almost all generated
	  code is the same as for i386, but it's still a bit unstable, and
	  slower than simulation because of excessive page faulting: code
	  patching isn't working yet. But FreeDOS boots. Only enabled for
	  $_cpu_emu="vm86", not for the default "off" for now. Marked
	  InCompiledCode as volatile to simplify asm constraints.

	* [r1634] src/emu-i386/simx86/codegen-sim.c,
	  src/emu-i386/simx86/codegen-sim.h,

	  src/emu-i386/simx86/cpu-emu.c, src/emu-i386/simx86/interp.c,
	  src/emu-i386/simx86/trees.c:
	  cpuemu: replaced use of inline asm __memcpy by memcpy. GCC does a
	  good job now and asm __memcpy isn't portable.

	* [r1633] src/emu-i386/simx86/codegen-x86.c,
	  src/emu-i386/simx86/fp87-x86.c:
	  cpuemu: fix asm compilation on x86-64.

2006-10-24  Bart

	* [r1632] src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/emu-i386/simx86/sigsegv.c, src/plugin/commands/builtins.h:
	  Improve cpuemu fault handling and diagnostics; avoid a few more
	  page faults in DOSEMU code.

	* [r1631] src/base/init/config.c, src/dosext/dpmi/dpmi.c,
	  src/emu-i386/simx86/codegen-x86.c, src/include/emu.h:
	  simx86: shortened asm code, check correct CPU feature flags for
	  prefetcht0, and fix DPMI Jazz Jackrabbit crash with
	  $_cpu_emu="vm86".

2006-10-23  Bart

	* [r1630] src/base/init/parser.y.in,
	  src/emu-i386/simx86/codegen-x86.c, src/emu-i386/simx86/cpatch.c,
	  src/emu-i386/simx86/sigsegv.c, src/include/cpu-emu.h:
	  Link in most of the JIT code for x86-64. Small crucial parts
	  still disabled.

	* [r1629] src/arch/linux/debugger/Makefile,
	  src/arch/linux/dosext/sound/midid/Makefile,
	  src/tools/periph/Makefile:
	  Use LDFLAGS without -rdynamic to link misc binaries.

	* [r1628] etc/dosemu.conf, src/base/init/lexer.l.in,
	  src/base/init/parser.y.in, src/emu-i386/simx86/Makefile,

	  Select JIT or simulated CPU emulation at runtime instead of at
	  compiletime.

2006-10-22  Bart

	* [r1627] src/arch/linux/async/signal.c,
	  src/arch/linux/async/sigsegv.c, src/emu-i386/cpu.c,
	  src/include/emu.h:
	  Replaced tls_setup hack with something just a little cleaner. The
	  64bit fs and gs bases are restored in signal handlers. To avoid
	  an expensive syscall it is first checked if the bases really need
	  to be set by comparing the memory fs/gs and the original base
	  point to. There is a very small chance that that involves a page
	  fault, which needs to be fixed up.

	* [r1626] src/include/cpu.h:
	  Fix FPU save/restore on x86-64.

2006-10-20  Bart

	* [r1625] src/base/misc/Makefile, src/base/misc/fatfs.c,
	  src/base/misc/fatfs.h, src/base/misc/fatfs_boot.S:
	  Simplify linking in fatfs_boot.S, similar to bootsect.S before.

	* [r1624] src/tools/periph/Makefile, src/tools/periph/bootsect.S,
	  src/tools/periph/bootsect.h, src/tools/periph/mkfatimage.c,
	  src/tools/periph/mkfatimage16.c:
	  Link compiled bootsect.S directly into mkfatimage* instead of
	  using hex. Get rid of things that are overwritten in bootsect.S;
	  I can't find anything left (C) Peter Norton.

2006-10-19  Bart

	* [r1623] src/base/bios/Makefile, src/env/video/remap_asm.S:
	  Adjustments for older GCCs and 64-bit noexecstack.

	* [r1622] src/base/bios/Makefile, src/base/bios/bios.S,
	  src/dosext/dpmi/dpmisel.S, src/env/video/Makefile,
	  src/env/video/remap_asm.S, src/env/video/vesabios.S,
	  src/env/video/vesabios_pm.S, src/include/macros86.h:
	  Added sections to assembly files to mark a non-executable stack.
	  (suggestion from James Courtier-Dutton, linux-msdos). For bios.S
	  and vesabios.S it was necessary to compile without intermediate
	  linking, which adds a few "-bios_f000"'s but simplifies Makefiles
	  considerably.

	* [r1621] src/dosext/dpmi/dpmi.c:
	  Fix C problem with wrongly placed label.

	* [r1620] src/arch/linux/async/signal.c,
	  src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmisel.S, src/dosext/dpmi/dpmisel.h:
	  Use IRET to jump into DPMI client code on x86-64. It's nice
	  because it pops up ss:esp even for same-privilege transfers from
	  long mode. To avoid the infamous 16-bit stack ESP corruption
	  issue the iret stack frame is allocated at 0x100000000 or a
	  similar address with bits 16-31 zero.

2006-10-18  Bart

	  src/include/cpu.h, src/include/emu.h, src/include/vm86plus.h,
	  src/plugin/term/terminal.c:
	  Cleaned up vm86plus.h. Created a new init_handler function in
	  signal.c which takes care of flags, %fs, %gs etc. dis8086 64-bit
	  compat. Create dpmi_iret_setup for exiting signal handlers to
	  DPMI client code.

	  from 2asm via MAME and DOSBox.

2006-10-17  Bart

	* [r1617] src/plugin/commands/unix.c:
	  Fixed quiet switching for dosemu in dumb mode with a given
	  command.

2006-10-12  Bart

	* [r1616] src/dosext/dpmi/dpmi.c, src/dosext/dpmi/dpmisel.S:
	  Improve direct DPMI switch jmp for x86-64: don't use instructions
	  that change flags after popf, eliminate use of r10, and tell gcc
	  that r8 and r9 are clobbered.

2006-10-11  Bart

	* [r1615] src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmi.h, src/dosext/dpmi/dpmisel.S,
	  src/dosext/dpmi/dpmisel.h:
	  Removed sigsetjmp/longjmp usage for DPMI again. A tiny amount of
	  assembly can do it more efficiently (saves the sigprocmask
	  syscall that sigsetjmp makes).

2006-10-10  Bart

	* [r1614] src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmisel.S, src/dosext/dpmi/dpmisel.h,
	  src/emu-i386/cpu.c, src/emu-i386/simx86/cpu-emu.c:
	  Implemented native DPMI code execution for x86-64. Only tested
	  with a simple Openwatcom "wcc hello.c" but that works. It needed
	  a few workarounds involving %ss and in particular a nasty hack
	  for %fs (used for TLS).

	* [r1613] src/emu-i386/simx86/codegen-x86.h,
	  src/emu-i386/simx86/codegen.h, src/emu-i386/simx86/cpu-emu.c,
	  src/emu-i386/simx86/protmode.c, src/include/emu-ldt.h:
	  Change lots of long * to int * in CPUEMU. Now basic DPMI works
	  for $_cpu_emu="full" on x86-64.

	* [r1612] src/arch/linux/async/debug.c:
	  Add an extra backtrace without full (in case gdb with full
	  fails), and a simple backtrace using glibc backtrace(), for
	  suid-root.

	* [r1611] src/base/async/int.c, src/dosext/dpmi/dpmi.c,
	  src/include/Asm/ldt.h:
	  Changed lots of longs to int in the DPMI and LDT code, and a few
	  for int15(extmem). Now DPMI LDT entry allocation works for 64bit.

	* [r1610] src/arch/linux/mapping/mapping.c:
	  Map DPMI, LFB, and hardware RAM high memory into the first 2G of
	  address space on x86-64 using MAP_32BIT.

	* [r1609] src/arch/linux/debugger/mhpdbgc.c,
	  src/emu-i386/simx86/sigsegv.c, src/include/mhpdbg.h:
	  Fix dosdebug (ldt, symbol reading) and cpu exception printf for
	  64-bit.

	* [r1608] src/dosext/dpmi/dpmi.c,
	  src/emu-i386/simx86/codegen-sim.c, src/include/bitops.h:
	  Replaced simulated BITOP code by non-self-modifying code, adding
	  the used change_bit and find_bit_r inline functions to bitops.h.
	  Some more long->int conversions for 64bit compatibility.

2006-10-08  Bart

	* [r1607] src/include/cpu.h, src/include/timers.h:
	  Fix rdtsc (fixes random slow-downs and hangs) and unix.com in
	  64-bit. Getting more usable.

	* [r1606] src/plugin/sdl/sdl.c:
	  Tweak fullscreen mode selection (for 320x200 you now get 640x400
	  instead of 640x350) in SDL, and work around a crash for fbdev
	  etc.

	* [r1605] src/plugin/X/X.c, src/plugin/X/screen.c,
	  src/plugin/X/screen.h, src/plugin/sdl/sdl.c:
	  Move X dependent part of copy/paste support into screen.c.
	  Support copy/paste with SDL/X11.

	* [r1604] src/plugin/X/X_keysyms.c, src/plugin/X/keyb_X_keycode.c:
	  Fix Alt-Gr handling with Xorg 7.1 (Reinhard & Michael Karcher)

	* [r1603] src/env/video/vc.c:
	  Fix i386 compilation.

	* [r1602] default-configure:

	  src/include/cpu-emu.h, src/include/cpu.h, src/include/emu.h:
	  Implemented proper x86_64 signal handling. Have just one sigalrm
	  handler. Fix error() to not mysteriously give different output on
	  stderr compared to boot.log. Very basic stuff works now (freedos
	  dir/exitemu).

2006-10-07  Bart

	* [r1599] src/env/video/vgaemu.c, src/include/vgaemu.h:
	  Make vga.mem.scratch_page a void * to avoid having to shift all

2006-10-06  Bart

	  First batch of x86-64 compatibility changes, mostly relating to
	  integer to pointer conversions. instremu is most affected.

2006-10-05  Bart

	* [r1594] src/arch/linux/Makefile.main:
	  Correct "tail +9" command to "tail -n +9". Closes #1516259.

	* [r1593] src/arch/linux/debugger/dis8086.c, src/dosext/misc/emm.c,
	  src/env/video/vc.c:
	  Fix gcc-4.2 warnings.

	* [r1592] src/arch/linux/mapping/mapfile.c,
	  src/arch/linux/mapping/mapping.c,
	  src/arch/linux/mapping/mapshm.c, src/base/misc/hma.c,

	  src/env/video/matrox.c, src/env/video/vc.c,
	  src/env/video/vgaemu.c, src/include/mapping.h:
	  Change mapping definitions to be more similar to the libc
	  prototypes, to save on casting (particularly for x86-64, later).
	  Handle alias maps via a separate alias_mapping() function because
	  here are two pointers instead of pointer + offset.

	* [r1591] src/include/memory.h:
	  Fix gcc warning in cmos.c.

	* [r1590] src/dosext/dpmi/dpmi.c, src/emu-i386/simx86/cpu-emu.c:
	  Basic cpu-emu DPMI fixes. At least Jazz Jackrabbit starts now,
	  but it's still not very stable.

	* [r1589] src/arch/linux/async/signal.c,
	  src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmi.h, src/emu-i386/simx86/cpu-emu.c,
	  src/include/cpu-emu.h, src/include/cpu.h:
	  Do not store the dpmi retcode in _eax any more, but return it
	  using the normal C mechanism. There are also some basic cpuemu
	  DPMI fixes.

2006-10-04  Bart

	* [r1588] src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmi.h, src/dosext/dpmi/dpmisel.S,
	  src/dosext/dpmi/dpmisel.h:
	  Clean up unused returns, marking functions "noreturn". Move some
	  some more asm to dpmisel.S, and make dpmisel() as small as
	  possible. Using dpmisel() as %cs for the intermediate jmp just
	  confuses the selector checks so this isn't implemented after all.
	  Avoid various casts.

	* [r1587] src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmi.h, src/emu-i386/cpu.c,
	  src/emu-i386/simx86/sigsegv.c, src/env/video/vgaemu.c,
	  src/include/cpu.h:
	  Remove _emu_stack_frame. Use a special static eflags_fs_gs struct
	  to save and restore those, and handle the rest using the real CPU
	  segment registers, using asm macros.

	* [r1586] src/dosext/dpmi/dpmi.c:
	  Eliminate one-time indirect DPMI switch to save FPU context. It's
	  not necessary any more after inheriting it from vm86.

2006-10-03  Bart

	* [r1585] src/dosext/dpmi/dpmi.c, src/emu-i386/cpu.c,
	  src/emu-i386/do_vm86.c:
	  Do not save and restore the emulator FPU state (only VM86 and
	  DPMI states): savefpstate (fsave) also resets the current FPU
	  state which is good enough for calling FPU-using routines.

	* [r1584] src/base/dev/misc/rtc.c:
	  Replace 1e6 by 1000000: no need for floating point here.

	* [r1583] src/base/bios/bios.S, src/dosext/dpmi/Makefile,
	  src/dosext/dpmi/dpmi.c, src/dosext/dpmi/dpmisel.S,
	  src/dosext/dpmi/dpmisel.h, src/dosext/dpmi/msdos.c,
	  src/dosext/dpmi/vxd.c, src/include/bios.h:
	  Move all protected mode HLTs and the intermediate direct DPMI jmp
	  to a seperate memory area from the BIOS, and point dpmi_sel() to
	  that.

2006-10-01  Bart

	* [r1582] configure, configure.ac:
	  Better fix for configure (the previous one only worked with one
	  option).

2006-09-30  Bart

	* [r1581] configure, src/include/config.h.in,
	  src/plugin/kbd_unicode/configure,
	  src/plugin/kbd_unicode/include/kbd_unicode_config.h.in,
	  src/plugin/sdl/configure:
	  Regenerate autoconf-generated files with autoconf 2.60a.

	* [r1580] configure.ac:
	  Fix argument issue with calling default-configure from configure.

	* [r1579] src/base/init/lexer.l.in, src/base/init/parser.y.in:
	  Use strtoul to parse dosemu.conf numbers so that hardware ram etc
	  work with negative addresses.

	* [r1578] etc/dosemu.conf, src/arch/linux/mapping/mapping.c,
	  src/base/misc/utilities.c, src/dosext/dpmi/memory.c,
	  src/include/mapping.h, src/include/utilities.h:
	  Use non-zero mmap target addresses without MAP_FIXED. This avoids
	  the need to parse /proc/self/maps. Make (auto) the new default
	  for $_dpmi_base. Change dpmi_alloc_pool for $_dpmi_base=(auto) to
	  reject negative addresses; it will then try an address 128MB past
	  the current brk limit which is fairly close to the old default.

	* [r1577] src/arch/linux/mapping/mapfile.c, src/env/video/vgaemu.c:
	  Move VGAEMU LFB memory out of the shared memory pool (it can be
	  anonymous). Now the memory pool can be mmap'ed rw instead of rwx
	  (better protection with exec-shield); just the DOS-accessible
	  memory is rwx.

	* [r1576] src/arch/linux/mapping/mapfile.c:
	  Implemented workaround for failed PROT_EXEC on noexec shm mounts.

	* [r1575] src/arch/linux/async/signal.c,
	  src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmi.h:
	  Use sigsetjmp() and siglongjmp() to enter and return from DPMI,
	  instead of fiddling with CPU registers using assembly language,
	  greatly simplifying direct_dpmi_switch(). It will also be
	  portable to x86-64. The changes are as minimal as possible but
	  more cleanups can certainly be done (most of the _emu_stack_frame
	  can be eliminated for instance).

2006-09-28  Bart

	* [r1574] src/base/bios/bios.S, src/dosext/dpmi/dpmi.c,
	  src/include/memory.h:
	  Use a special mmap'ed area for direct dpmi switching. This avoids
	  using the BIOS for data transfers and (wrt Stas' solution) has
	  the advantage of working with -fpic/pie

2006-04-29  Bart

	* [r1573] src/plugin/term/terminal.c:
	  Streamline terminal character write and ACS table construction
	  routines. Don't use ACS characters when it's not necessary (the
	  external charset already contains the required characters); this
	  helps with $_external_charset="cp437" on xterm -k8 -font vga
	  (Putty makes no difference). Only use ACS characters that are
	  specified by the relevant terminfo entry.

	* [r1572] src/plugin/X/X.c:
	  Enable use of unicode fonts for $_X_font, such as uni-vga, but
	  also misc-fixed*iso10646-1. The logic assumes DOS codepage
	  encoding for fonts with 256 or less characters, and UCS-16
	  otherwise.

	* [r1571] src/base/bios/bios.S, src/dosext/dpmi/dpmi.c,
	  src/include/memory.h:
	  Apply %cs segment limit workaround for direct_dpmi_switch on
	  exec-shield kernels. Fixes #1478658: Crash on every DPMI program
	  under Linux 2.6.16.

2006-04-11  Bart

	* [r1570] src/include/pci.h:
	  Avoid problems with <sys/pci.h> by just defining the PCI_
	  constants ourselves.

	* [r1569] src/base/init/config.c:
	  Moved -2 -3 etc option parsing after config file parsing so they
	  actually work.

2006-03-11  Bart

	* [r1568] src/env/video/render.c:
	  Scale small modes towards ~640x400 (shows testcase for #1443448
	  in the right proportions)

2006-03-05  Bart

	* [r1567] src/emu-i386/cputime.c:
	  Fix TSC handling during DOSEMU freeze. Fixes #1441256 keyboard
	  issue (current cvs)

2006-03-04  Stas

	* [r1566] src/base/bios/bios.S, src/dosext/dpmi/dpmi.c,
	  src/dosext/dpmi/dpmi.h, src/dosext/dpmi/msdos.c,
	  src/dosext/dpmi/msdos.h, src/include/bios.h:
	  Preserve the PM regs unpon the realmode interrupts. That allows
	  to merge the msdos_pre_exec() with msdos_pre_extender(), and
	  msdos_post_exec() became completely unnecessary and removed. Also
	  cleaned up the dpmi_init() and removed the "psp" field from the
	  DPMI struct (msdos.c now handles PSP)

2006-03-04  Bart

	* [r1565] src/tools/periph/Makefile:
	  Fix dependency for bootsect.h after make distclean.

2006-03-04  Stas

	* [r1564] src/dosext/dpmi/dpmi.c, src/dosext/dpmi/dpmi.h,
	  src/dosext/dpmi/msdos.c, src/dosext/dpmi/msdos.h:
	  Remove wrong env-mangling code (#1442375)

2006-03-04  Bart

	* [r1563] src/include/vc.h, src/tools/tools86.c:
	  Fix GCC warnings.

	* [r1562] src/commands/Makefile, src/plugin/commands/Makefile,
	  src/tools/Makefile, src/tools/periph/Makefile:
	  Use dependencies for commands and tools; using intermediate .o
	  files was the easiest (and GCC-version-independent) way to do
	  this. Fixes #1415598 (build deps for commands are missing).

2006-03-04  Stas

	* [r1561] src/base/misc/utilities.c:
	  reapplying

	* [r1560] configure.ac:
	  reapplying

2006-03-04  Bart

	* [r1559] src/env/video/render.c:
	  Dirty everything in vgaemu re-inits. Fixes #1407567 (vgaemu
	  problem with stdemo).

2006-03-03  Bart

	* [r1558] (all directories)
	  Set ignore properties on directories.

	* [r1557] src/base/serial/ser_init.c, src/dosext/misc/xms.c:
	  Replace $Header$ by $ Id: $ (svn only understands $ Id: $)

	* [r1556] src/commands/cmdline.c, src/commands/detect.h,
	  src/commands/dosdbg.c, src/commands/emulib.h,
	  src/commands/emumouse.c, src/commands/lredir.c,

	  src/commands/turboc.cfg, src/commands/unix.c,
	  src/commands/xmode.c:
	  Set svn:eol-style to CRLF for all DOS text files.

2006-02-28  Bart

	  src/env/video/vgaemu.c, src/include/memory.h:
	  Implement int15/ax=e820 (necessary for fdxxms.sys), and some
	  memcheck infrastructure to construct the memory map. Avoid
	  putting nul characters in the debug log (use 'e' for emulated
	  hardware RAM).

	* [r1464] src/env/video/render.c, src/env/video/vgaemu.c:
	  Take the blanking register into account for determining height

	* [r1462] src/base/bios/int10.c:
	  Fix offset to copy font data from in int10/ax=11*0

	  Search and replace DPMI_CLIENT.is_32 by Segments[_cs>>3].is_32 at

	  include/memory.h:
	Avoid using LOWMEM for the non-const addresses.
	This fixes iplay (again), as it read()s directly to the EMS frame.
	Also, moved dos_read/write to dos2linux.c to make them globally
	available. And removed the __builtin_constant_p() check in LINEAR2UNIX -
	gcc might still be able to optimize the const addresses, but falling
	back for dosaddr_to_unixaddr() will happen less frequently.

	* src/: commands/ems.S, include/emm.h, dosext/misc/emm.c,
	  dosext/misc/emm.h:
	- Implemented the version checking for ems.sys. Whoever forgets
	to update one, will now get the deserved punishment.
	- Since the bug was in the UMB hook, not in the EMS driver, made
	ems.sys not to install the UMB hook too, if dosemu refused EMS.
	("EMS 4.0.1" was very funny :-)

	* src/commands/ems.S:
	Avoid using "lret $2" - this doesn't restore the IF flag, causing
	the program to lock up (noticed with iplay).
	Bumped up the version. Some version checking is really needed here.
	Important: bios.S have to be inspected for the like things.

	Added the standalone mode - midid can now launch timidity itself.
	Added the capture mode - midid can now capture and redirect the
	sound generated by timidity.
	Nothing of the above works with the current timidity, and so the
	usage description of the new params is disabled.
	Also changed the default timidity timeout to 0 (no timeout).

	BIOS setup calls iodev_reset. Moved iodev_init after priv_drop() and priv.
	needing inits out of it. Add disk, printer, ipx, pktdrvr init/reset to

	Repair config.vbios_post=1 + VESA
	VESA pre-boot information gathering uses complete /dev/mem information.

	* src/base/bios/bios.S:
	Moved R/W data in the BIOS to 0xd000, and use indirect jumps/calls instead

	Added IBM signature at 0xe000.

	Move the BIOS parts under 0xf4000 back beyond 0xfc000.
	Change default EMS page frame to 0xe4000 so that the new space is used

	* src/: base/async/int.c, emu-i386/do_vm86.c, include/int.h:
	Split off do_int_from_hlt() from do_int(). It simplifies some processing

	* src/dosext/dpmi/dpmi.c:
	Cache the pointer to the DPMI_CLIENT struct where in_dpmi can
	change, and pass it to return_to_dosemu(). This fixes the watcom
	problem and allows some cleanups. The further cleanups can be
	to use that pointer always, not only for return_to_dosemu(), but
	I think only return_to_dosemu() really cares.

2005-09-11  Bart

	* src/emu-i386/do_vm86.c:
	Remove recursion check for dpmi ints 0x1c,0x23,0x24 that is no longer

	tar 1.14 (e.g. FC4) enabled the opposite of "--no-overwrite-dir" by default.

	At "make install" time, a symbolic link
	"/usr/local/share/dosemu/freedos/tmp" is made to point to "/tmp".  On the
	second invocation of "make install", dosemu-freedos-bin.tgz is unpacked to

2005-09-05  Bart

	* src/plugin/sdl/sdl.c:
	Always grab if fullscreen is set at init. This fixes the mouse in SDL
	fbdev mode.

	* src/plugin/sdl/: mouse_SDL.c, sdl.c, sdl.h:
	Added support for fullscreen toggling, mouse and keyboard grab (can't

	SDL plugin.

	* src/: base/misc/dos2linux.c, include/dos2linux.h, plugin/X/X.c,

	Use ldt_buffer for simx86's LDT. Merge the codes that update the cached
	LDT. I thought the simx86 version was the nicer of the two.

	* src/dosext/dpmi/dpmi.c:
	Added extra check in get_ldt to make sure that the simx86 LDT matches the

	Use a few header adjustments to avoid #ifdef's in the main code.
	Make check_munprotect e_check_munprotect, a global function that only

2005-09-03  Bart

	* src/arch/linux/async/sigsegv.c:
	Localise variables csp and i in dosemu_fault1. This is a workaround for

	Use macros and straight-asm for the rep instructions.

	* src/emu-i386/simx86/cpatch.c:
	Use straight asm without function overhead. This allows to eliminate _DEBUG
	defines. Use macros to reduce near-duplicate code.

	* src/emu-i386/simx86/cpatch.c:
	Use wri_8 etc. functions in stub_movsb etc. This reduces assembly and

	Replace symbolic link system for simx86 by conditional compilation.
	Fix a dpmi_eflags and case label range issue with codegen-sim.

	* src/emu-i386/simx86/cpatch.c:
	Allow gcc -O2 for newer versions of GCC (need __attribute__((used)))
	Converted some of the assembly in the stubs to C
	Avoid mprotect/munprotect where possible by making use of the aliased

	they are not strictly bios related.

2005-08-23  Stas

	Unblock async signals in instremu.

	* src/arch/linux/async/signal.c:

	a mirror map of the 0-1MB+64KB area, but not r/w protected. So we can
	access everything from dosemu's main code without causing page faults,
	or necessary mprotect adjustments. NULL page debugging also becomes a
	little cheaper this way.

	* src/base/bios/int10.c:
	Fix not yet existing lowmem_alias.

	* src/base/: init/init.c, mouse/mouse.c:
	Use READ/WRITE* when accessing DOS memory.

	* src/: include/cpu.h, emu-i386/simx86/cpu-emu.c:
	Replace asm push/pop macros by C code, using READ_BYTE etc.
	Use READ/WRITE_WORD for IOFF, ISEG, and SETIVEC.

	* src/: env/video/text.c, include/video.h:
	Moved ATTR and CHAR macros from video.h to text.c. They access internal
	vgaemu RAM, so no need for READ_BYTE etc.

	* src/base/bios/: int10.c, int17.c:
	Use macros to access BIOS variables in int10.c.
	int17.c does not need MUNPROT emulator stuff, because it's all read only.

2005-08-21  Stas

	* src/base/mouse/mouse.c:
	Don't disable the mouse driver on ax=0x1f.
	RBIL says the driver gets really disabled only if you install
	the intvector returned by this function, so it looks like otherwise
	this function does nothing.
	This solves the problem with mcity, for which I previously had
	to use dosbox:)

	* etc/global.conf, src/base/bios/Makefile, src/base/bios/int17.c,
	  src/base/dev/misc/lpt.c, src/include/lpt.h:
	Rewrote int17 (thanks to Bochs) to interface to the parallel port hardware,
	so that it works with emulated ports and real i/o ports.
	Implemented basic emulated parallel port hardware that deals with the
	printer. $_printer_commands should be allowed from .dosemurc for suid-root.
	This implements RFE #830601.

2005-08-17  Bart

	* src/base/misc/disks.c:
	Added very basic floppy i/o port motor control handling, just to turn it
	off for now.

	* src/base/: async/int.c, bios/bios.S:
	Let INT 8 increment, instead of just set, the midnight flag when the time
	is right. This helps when INT 1A isn't called for longer periods of time,
	and is consistent with some other BIOSes.
	Use READ_DWORD etc. in int.c; small optimization; flag floppy timeout to
	controller (note that the floppy controller port 0x3f2 isn't emulated yet).

	* src/plugin/sdl/keyb_SDL.c:
	Handle all SDL keysyms including keypad, prtscr etc. Fixes #1252147

	* src/base/bios/int10.c:
	Set correct page size for int10/ah=5 in graphics modes. Fixes #1255178

2005-08-16  Bart

	* src/: base/bios/bios.S, emu-i386/do_vm86.c:
	Replace "int xx" in bios.S trampoline by hlt. Minimal change: further
	cleanups are possible.

2005-08-15  Clarence

	* dist/dosemu, src/base/init/config.c:
	Wrapper script: don't pass "dosemu.bin" as argv[0], pass the wrapper scr
	ipt name instead.

	config.c: Look for --version/--help arg anywhere in the argv[] list
	(so as to not complain on "xdosemu --help" which prepends a -X to argv[]).
	Don't print out "xdosemu = dosemu -X" if already using xdos/xdosemu.

	* src/plugin/kbd_unicode/serv_backend.c:
	Got tired of the ocasional keypress duplications and increased

2005-07-24  Bart

	* src/base/init/parser.y.in:
	No need (and wrong) to free Path_cdrom[which].

	* src/: emu.c, emu-i386/simx86/cpu-emu.c:
	Allow cpuemu when $_rdtsc=(off). It uses RDTSC nevertheless (so should
	check for 586), but now with the timer code just using gettimeofday().

	* src/: arch/linux/async/signal.c, emu-i386/cputime.c,
	  include/timers.h, base/init/init.c, dosext/dpmi/memory.c,
	  emu-i386/simx86/emu86.h, dosext/drivers/aspi.c:
	Replaced HZ by the more modern sysconf(_SC_CLK_TCK).
	The sigalarm handler now updates the time system counter base, so our
	TSC timer is a hybrid just like the one in the Linux kernel. This avoids
	DOS time slow downs because of inactive idle cpu's etc. Correct backtracing
	in emu86.h.

	Applied (by popular demand) the new timemode patch from Andrew Brooks.
	This should have a positive effect of having the cmos values in

	New option is added to dosemu.conf.

	  src/emu.c, src/include/cpu.h, src/plugin/sdl/Makefile,
	  src/plugin/sdl/Makefile.conf.in, src/plugin/translate/Makefile:
	Add support for compilation on x86-64.

	* src/env/video/instremu.c:
	We must use "q" and not "r" in byte-operating asm instructions to avoid
	GCC telling us "Error: bad register name `%sil".

	* src/dosext/dpmi/: dpmi.c, dpmi.h:
	Moved ds, es, fs, and gs check selector code into a function.
	Allow 1, 2, and 3 as null selectors. They sometimes seem to occur on
	x86-64. Simplified ValidSelector(): in practice it only needs to check for
	the LDT bit.

	* src/base/mouse/mouse.c:
	We should only erase a text mouse cursor if it's native and drawn, not
	unconditionally if it's non-native.

	* src/arch/linux/async/signal.c:
	Removed unused variable kernel_sa.

	* src/emu-i386/simx86/codegen-arch.c:
	Actually enable the hack to get bgidemo (and doom) working.

	* src/: emu-i386/simx86/cpu-emu.c, emu-i386/simx86/sigsegv.c,
	  env/video/vgaemu.c:
	Make simx86 more functional with DPMI code (both native and emulated).
	Adjusted bogus ((int)_cr2 < 0) test. Signal handlers use the signal stack
	and perhaps queue, and restore eflags, fs and gs. Revert the meanings of
	config.cpuemu==2 and 3. The fault handler takes better care of VGAEMU.

	  src/dosext/dpmi/dpmi.c, src/base/init/lexer.l.in,
	  src/base/init/parser.y.in, src/include/cpu-emu.h:
	Introduced new $_cpu_emu option to set to either "off", "vm86" or "full".
	config.cpuemu==4 now means full emulation, 3 means vm86 only.
	Adjusted DPMI to reflect this. CPUEMU's fault handler temporarily leaves
	the vm86-only emulator after a page fault if DPMI is active.
	Disabled non-emulated boot and vbios for now.

	As posted to dosemu-devel put without the usage() change:

	Config documentation cleanup and a little bit of getopt() fixing.

	Complete list of changes (it's smaller than it looks):
	- Remove unused, probably out-of-sync "struct debug_flags d"
	- Pass the same string to the 2 getopt calls and in sync with reality
	  (sometimes we were missing ":" or options entirely)
	- We need "--help" in addition to "--version" (I finally found out that
	  "--version" was the correct way to bring up the help, rather than triggering
	  a syntax error with "-h" :))
	- Remove unused "sizes" variable, group together code for handling obsolete
	  options
	- Print the bad character (not '?') when user types in incorrect option
	- usage():
	  # Remove "[-ABckballtheseareeitherwrongoroutofdateanyway]" etc. from the
	    description
	  # Remove non-existent options, obsolete options
	  # Document secret until now options like -S (so Bart, your SDL secret is out
	:))
	  # In other words, document all the options we have and be consistent with
	    the getopt string
	  # Move "%s --version" lower since it doesn't accept options
	  # Indent "%s --version" and "xdosemu [options]" for consistency with primary
	    command

	* src/base/misc/fatfs.c:
	Use e_dos_read() to load the FreeDOS kernel when cpuemu is active.
	Allows running dosemu without using vm86 at all, useful for x86-64.

	* src/emu-i386/simx86/: codegen-arch.c, cpu-emu.c, interp.c:
	The correct expression for the virtual flags in DPMI is
	get_vFLAGS(TheCPU.eflags)
	which gets the VIF from the vm86s structure.

	* src/emu-i386/simx86/: codegen-arch.c, interp.c, sigsegv.c:
	simx86: Corrected vga_read/write calls, and VGAEMU port list. Removed

	Replace dpmi_eflags with _EFLAGS in simx86. Not quite sure how correct this
	is. Copy the LDT table that dpmi_setup() put up into the simx86 LDT.
	With these changes simx86 works again for DPMI (not perfectly but...).

	* src/emu-i386/simx86/sigsegv.c:
	s/Logical_VGA/vga/

	* src/emu-i386/simx86/protmode.c:

	Respect the state of the keyboard_flags_3 instead of relying on
	the one remembered by dosemu (second part of #1230579)

	* src/dosext/mfs/: lfn.c, mfs.c, mfs.h:
	LFN MFS fixes: basic volume label for LFN findfirst, give "access denied"
	when trying to remove a non empty dir. Fixes VC move problem, #1238148;
	and cleanups: header files, replace MAXPATHLEN with PATH_MAX.

2005-07-19  Bart

	* src/env/video/: crtcemu.c, vgaemu.c:
	Modify vga_emu_adj_config to adjust VESA modes that are within bounds,
	in general < 2048x1024x8bpp. Setup the CRT mode init that way as well.

	* src/env/video/seqemu.c:
	Set vga.seq.data[4] to the correct value for VESA modes.

2005-07-18  Bart

	* src/base/mouse/mouse.c:
	Let mouse_move_absolute only cause a callback to (e.g.) perhaps warp the
	X cursor if the mouse was clipped.

	* src/base/bios/int10.c:
	Unconditionally set the bios cursor shape variable, even if set to
	invisible. This fixes a problem with DN.

	* src/env/video/vga.c:
	Don't check for the int10 location if $_vbios_post=(1).

2005-07-17  Bart

	* src/env/video/: crtcemu.c, vgaemu.c:
	Adjust some crtc registers in 8bpp vesa modes, and recognize them in
	the adjust config routine. Perhaps that allows a windows vesa driver to
	work.

	* src/base/: mouse/mouse.c, mouse/mousevid.c, bios/bios.S:
	Fix missing 0x typo in mousevid.c; check if the vesa mode was really set.
	The mode is now passed on the stack instead of in cx.

	* src/env/video/: text.c, vgaemu.c:
	Set video to off initially so that the screen won't get updated before the
	initial mode set. Also don't divide by zero in check_cursor_location.
	Fixes #1239421

2005-07-17  Stas

	* src/plugin/X/X.c:
	Properly track FocusIn/FocusOut X events (further fixing #920216)

	* src/: include/mouse.h, base/mouse/mouse.c:
	Replace mouse.rx and mouse.ry with a macros to reduce the
	amount of the variables we should keep in sync.

	* src/base/mouse/mouse.c, src/plugin/X/X.c:
	Move mouse pointer no matter whether it is visible or not

	Forgotten piece of the partial #920216 fix.

	  base/bios/bios.S, base/mouse/gcursor.c, base/mouse/mouse.c,
	  base/mouse/mousevid.c, base/mouse/mousevid.h:
	fix #1206135 by passing bx from vesa mode sets to the mouse mode set
	adjustments. This works for vgaemu and all fixed console vesa modes.
	However, don't draw any mouse cursor: gcursor.c doesn't know about
	LFBs, >8 bpp and bank switching.

	* src/base/init/parser.y.in:
	Removed a free() that was a tad too aggressive.

	  plugin/translate/config/plugin_parser, base/dev/misc/joystick.c,
	  base/dev/misc/lpt.c, plugin/term/mouse_xterm.c:

	mouse_xterm detection (which was also a leak).

	  arch/linux/async/debug.c, include/dosemu_config.h,

	Reintroduced dosemu_proc_self_exe, as it comes in really handy for dosdebug.
	Fall back to dosemu_argv[0] for older valgrinds and qemu if it's NULL.
	Plugged a small memory leak.

	* src/arch/linux/async/signal.c:
	Use RTLD_NEXT to find glibc's default (non-pthread) sigaction. Saves a
	bit of effort on our part. This technique is borrowed from Wine: if they
	can do it, we can do it too.

	* src/: env/video/vesa.c, base/bios/int10.c, env/video/console.c,
	  env/video/hgc.c, env/video/vgaemu.c, env/video/video.c,

	Remove dosemu_proc_self_exe. It doesn't work under qemu and

	looks useless.

2005-07-14  Bart

	* src/: base/misc/utilities.c, emu-i386/cpu.c, emu-i386/ports.c:
	Use fscanf directly instead of fgets and then sscanf. Avoids some
	arbitrarily sized buffers.

2005-07-13  Bart

	* src/base/bios/int10.c:
	Moved adjust_font_size into a function of its own instead of fiddling with
	the high word of mode in set_video_mode. Implement changing scanlines after
	mode sets so that "mode co80,43" really gives you 43 lines in xdosemu.

	- Fixed $_mapping="mapfile" by providing the separate ops for
	"mapfile" and "mapshm", otherwise one can't select.
	- Added "mapashm" option for the anon-shm mapping.
	- "mapshm" is now a default.

	Small fixes.

2005-07-12  Bart

	* src/: base/mouse/mouse.c, include/mouse.h, plugin/X/X.c:
	Made some mouse functions static, removed some unused mouse code.
	Re-enabled Mouse->set_cursor call in mouse_do_cur to be able to warp the
	X cursor. However, be more conservative and safer in warping than before:
	- don't warp if snap_X is active or if the mouse cursor is off.
	- ignore any events caused by pointer warps; they often triggered infinite
	  actions because the event could be different from what we warped to.
	In non grab mode this fixes some issues with SC2000 (dual mouse cursor),
	and VPA (vga planets assistant, clicking didn't move the cursor).

	* src/: base/bios/int10.c, include/memory.h:
	Program display start via crtc for mode sets in terminal mode; fix TEXT_SIZE
	This fixes some new issues with programs that use multiple pages in terminal
	mode.

	* src/: base/init/dev_list.c, plugin/term/mouse_xterm.c:
	Initialize video before mouse and don't use the native (text) cursor
	for the xterm mouse.

2005-07-11  Bart

	* src/plugin/: X/X.c, sdl/sdl.c:
	Revert X and SDL to use video_mode global variable for now. Necessary for
	VESA modes, in particular with z80s (spectrum emulator).

	* src/plugin/X/X.c:
	Correct MIT-SHM X error handling. It didn't work over remote X via ssh.
	Call leavedos from the X error handler, otherwise it leaves DOSEMU
	uncleanly.

	* src/base/bios/int10.c:
	We can't change the number of screen rows in terminal mode when adjusting
	the font size.

2005-07-10  Bart

	* src/: dosext/dpmi/msdos.c, env/video/instremu.c,

	for modified segment registers in msdos.c) in instremu.

	* src/: base/bios/int10.c, env/video/video.c, include/video.h:
	Eliminated video_subsys, *height and text_scanlines global variables.
	set_cursor_shape now takes care of setting the BIOS variable as well.
	Cleaned up int10/ah=f to work like a real video bios does.

	Moved video priv_init/init/close to iodev list; the init no longer needs to
	map any /dev/mem, it all comes from the register_hardware_ram list.
	Always boot via setting a video mode, or POSTing, not just on the console;
	use 0:449 for the mode. Remove most other mode setters.
	Use fake_call_to() where possible.
	Merged init_vga_card() with vga_post_init().
	Eliminated font_height global variable.

	Get rid of SCREEN_ADR(), use screen_adr() instead, which uses only BIOS

	Started merging set_video_mode() and X_set_video_mode()
	clear_screen() now clears the whole screen (all pages)
	video.c calls set_video_mode(video_mode) instead of clear_screen; this

	* src/dosext/dpmi/: dmemory.h, dpmi.c, dpmi.h, memory.c, msdos.c:
	Hopefully the last "huge cleanups" part.
	- Completed the msdos.c separation by not accessing any of the
	dpmi.c variables directly, use the DPMI API instead.
	- And there seem to be the off-by-one bugs that the segment
	limits were used as a length without +1, fixed.
	- Cleaned up the memory.c API again.
	With this state of affairs I was able to resync my DJGPP port
	of msdos.c rather quickly, so I think the code is now "clean enough".

	* src/dosext/dpmi/dpmi.c:
	Cleaned up the hack a little.

	* src/: base/async/int.c, dosext/dpmi/dpmi.c, include/int.h:
	First pass on introducing the Windows Hack (tm) that will allow
	to run the DPMI apps in a Windows Standard mode DOS prompt (hence
	eliminating the need for the DOS prompt support in an Enhanced mode).
	Now running the DPMI in DOS prompt apps is possible, but an attempt
	to switch back to Windows before the DPMI app terminates, will crash.

	* src/dosext/dpmi/: dmemory.h, dpmi.c, dpmi.h, memory.c, msdos.c,
	  msdos.h:
	Next round of the "huge cleanups":
	- Separated memory.c from dpmi.c by passing the root of the memory
	list as a parameter to all the memory.c functions.
	- The DPMI state structure can now be static.
	- Made msdos.c to not use memory.c directly - it now tracks the
	memory allocations itself, as it should under real DOS (backported
	the appropreate code from my DJGPP playground). This is not very
	effective under dosemu, but this is the only possible way under
	real DOS, and is also now unavoidable because msdos.c doesn't any
	longer have the root of the memory list to pass to the memory.c API.
	- Unfortunately the memory.h name is already taken, so the added
	header is called dmemory.h :(

	Next step in separating dpmi.c/msdos.c. dpmi.c no longer accesses
	the state struct of the API translator, but it now calls its
	hooks directly, while normally the translator should register
	that hooks via the DPMI API. This will, however, add an extra
	context switches under dosemu, so the current state is probably
	the most adequate for dosemu. A few extra hooks should not be
	a big problem for the DJGPP port either.

	* src/dosext/dpmi/: dpmi.c, dpmi.h, memory.c, vxd.c:
	- Remove the pre-client DPMI_SEL selector. It doesn't need to be
	per-client, we only have to be care to provide the 16bit and 32bit
	version of it separately. This way vxd.c no longer accesses the
	DPMI state structure directly.
	- Moved dpmi_setup() from memory.c to dpmi.c and make it to
	allocate the above two selectors.
	- Made LDT_ALIAS and PMSTACK_SEL really per-client this time
	(the old code that inherits them was forgotten to remove).

	moved there from the DPMI structure. msdos.c no longer accesses
	the DPMI structure, but the dpmi.c still accesses the translator
	structure - this can't be addressed without a big functionality

	Split the interrupt_function array into two sets, one for revectored

	* src/dosext/dpmi/msdos.c:
	From Japheth: added the translation of int21/ah=43h and ax=71a0h
	Make int21/ah=0 use ah=0x4c to work around some bugs in ms-dos.
	Path from Japheth.

	its final work.

	* src/: base/mouse/mouse.c, base/mouse/mouseint.c, env/video/X.c,
	  include/mouse.h:
	Fixed a diabolical rounding errors in mouse_move_relative(). That
	allowed to remove the hacks with Y coord multiplication, which, in
	turn, should fix all the recent and old sensitivity problems. Lets see.

	* src/: dosext/drivers/cdrom.c, plugin/commands/commands.c:
	- Resetting/reopening cdrom before ejecting helps to eject it more
	reliably.
	- Implemented "eject -t" for closing the tray.

2005-05-24  Stas

	* src/base/mouse/mouse_gpm.c:
	gpm-mouse can lock up dosemu if Gpm_GetEvent() is called on a
	non-blocking fd when there is no data - it then returns the
	random values in a mouse coords, which leads to bad results.
	Added the select() check to avoid the problem.

	Some fixes to dosemu.conf. Comments mainly, but also enabled the
	$_lfn_support. Any reasons why it was disabled?

2005-05-23  Stas

	Update ChangeLog with last changes.
2005-05-20  Bart

	* NEWS, src/env/video/vga.c:
	gcc warning; set date in NEWS

	* (almost all files)
	It's 2005 this year.

	* NEWS, doc/EMUfailure.txt, doc/README.txt, man/dosemu.1.in,
	  man/dosemu.bin.1.in, src/doc/HOWTO/EMUfailure.sgml:
	Documentation updates. Mostly grammatical stuff, and a clarification
	about framebuffer consoles: it was possible before with some video cards
	(e.g. SiS) but with others only with major problems (needing fbset after
	exitemu, not being able to switch consoles and then go back etc).

	* configure:
	Regenerated

	* etc/dosemu.conf, src/commands/ems.S:
	Soften language about external XMS drivers a bit. No need to rush
	dosemu-freedos users at the moment since the only known problematic
	program is MS MEM.

2005-05-20  Stas

	* NEWS:
	No need to mention svgalib since it doesn't work very well yet
	(lacks one small fix in svgalib), but mention the fact that dosemu
	can be started from under the fbcon.

	* NEWS:
	Some more news added. But do not mention tasmx since it was just a
	regression at some point after all (2005-02-24 namely)

	* configure.ac:
	Cosmetic about the svgalib detection.

2005-05-19  Bart

	* ChangeLog, NEWS, VERSION:
	NEWS and ChangeLog updates for 1.3.2.

2005-05-10  Bart

	* src/dosext/misc/xms.c:
	Fix the XMS_RET() macro; and making it a function is more efficient.
	Added some comments to hopefully make sure the same bugs don't creep in
	again. This fixes Aladdin's issues with XMS.

2005-05-09  Bart

	* src/base/misc/fatfs.c:
	Don't scan files on fatfs drives for FreeDOS, as this DOS has these
	drives redirected early enough for int13 never to be necessary.
	This can save quite a bit of startup time.

	* src/: base/async/int.c, dosext/mfs/mfs.c, include/redirect.h:
	If the CDS changes, try to redirect any fatfs drives that did not fit in
	the CDS before. This may happen when FreeDOS changes LASTDRIVE from
	config.sys, and more than 4 fatfs drives are defined.

2005-05-08  Bart

	* etc/dosemu.alias, etc/vga10x24.bdf, etc/vga12x30.bdf,
	  etc/vga8x19.bdf, src/arch/linux/Makefile.main:
	Added some more vga fonts, which more or less match 640x480, 800x600
	and 1024x768 resolutions. Thanks to Martin Reuber, OFD Kiel,
	German Fiscal Administration

2005-05-06  Stas

	* src/env/video/: vga.c, vbe.c:
	- Make do_int10_setmode() to do something more than just locking up
	the video bios.
	- Disabled the "special memory mode" - Matrox G550 doesn't honour
	the bit15 (even for that mode!), so the memory was cleared before
	saving. By the way, Matrox can handle our banked saving/restoring
	very well, but Radeon 7500 miserably fails on our bankswitching code.
	- Disabled the "set mode before restore" hack - that never worked
	because of the both the above bugs, it only makes problems.
	- Restoring the ext regs is necessary after saving/restoring the video
	memory (well, without using the "special memory mode" it may not be
	necessary, but I added it to stay safe).

	This makes the console VESA driver pretty much usable.

	* src/dosext/dpmi/msdos.c:
	Really fix int21h/ah=38h this time! tasmx is now finally... yuck

	* configure, configure.ac:
	Re-fix auto setting for target-cpu.
	Use -Wno-pointer-sign for gcc-4.0 to avoid obscuring really useful warnings
	for now.

	* src/plugin/sdl/Makefile:
	Fix makefile in previous commit.

	* src/plugin/sdl/: Makefile, configure, configure.ac,
	  config/plugin_config.h, config/plugin_config.h.in:
	Use include/sdl_config.h[.in] included in config/plugin_config.h just like the
	kbd_unicode plugin does. This avoids the "mkpluginhooks-before-configure"
	problem.

	* configure, configure.ac, default-configure:

	Remove the S-Lang plugin. DOSEMU now cooperates nicely with all SLang
	libraries that are present in Linux distributions, so it is no longer
	necessary. Made a comment about some minor issues with the various
	library versions in existence.
	If no slang-devel library is installed, DOSEMU can now compile without
	terminal support.

	* doc/README.gdb:
	correct typo

	* src/: plugin/term/Makefile, plugin/term/mouse_gpm.c,
	  base/mouse/Makefile, base/mouse/mouse_gpm.c:
	Move mouse_gpm.c from src/plugin/term to src/base/mouse.

	  env/video/vgaemu.c, include/vgaemu.h:
	- Fixed 40h:4eh bios value (current video page start)
	- Made the gfx-cursor code to take that value into an account
	(works in Orbits3 properly now)
	- Disabled the X-specific code for gfx-cursor. This can introduce
	the regressions, but as the gfx-cursor for X was added just a few
	days ago (what was that X-specific code then, if there wasn't a
	gfx-cursor under X before?), the regressions on it are not a problem.

	* src/dosext/mfs/mfs.c:
	Off-by-one error in MFS code causes lock-ups (bug #1189666)

2005-04-27  Stas

	* src/dosext/dpmi/msdos.c:
	Fixed int21h/ah=38h translation to get tasmx to work. Yes, tasmx
	used to work sometime in the past, but the bug was always there,
	so it couldn't work properly.
	Also fixed 2 gcc4 warnings.

	* src/env/video/X.c:
	Fullscreen mode can now always enable mouse grab.

	* src/base/: init/lexer.l.in, init/parser.y.in, misc/disks.c:
	Applied patch #845119 - 2.8M floppy support.
	The patch was there for 1.5year already - enough!

	* src/: env/video/instremu.c, env/video/vgaemu.c, include/vgaemu.h:
	Moved instremu to the new vga helpers, Logical_VGA_xxx can now be static.

	* src/: include/vgaemu.h, base/mouse/gcursor.c, base/mouse/mouse.c,
	  env/video/vgaemu.c:
	- Added the vga memory access helpers
	- Moved gfx-cursor code to use that helpers
	- Enabled the gfx mouse cursor code under X

	GFX mouse cursor now works under X!

2005-04-24  Stas

	* src/arch/linux/dosext/sound/linux_sound.c:
	Fix recent small regression with sound code (kryptegg works again)

	* src/env/video/vc.c:
	Remove unused (and crap) DUMP_VIDEO

	* src/base/mouse/: gcursor.c, mouse.c:
	Another small step towards the gfx mouse cursor under X.

	* src/env/video/svgalib.c:
	Trying to resurrect the svgalib support.
	It really works much faster than our VESA driver (due to the
	use of the native driver) but it doesn't save the video memory,
	so there may be some problems.

	* configure.ac:
	Added proper svgalib checks. New svgalibs are better, but we can't
	even link the old ones in.
	But not enable it for now - svgalib still misses one very small
	patch that I forgot to submit, and so it crashes, damn. Will have
	to wait for the next version again :(((

	* src/include/vc.h:
	Increase MAX_X_REGS as per the new svgalib.

	* src/env/video/: vc.c, vga.c:
	Disable dump_video(). It can crash if the MAX_X_REGS of dosemu
	mismatches with MAX_REGS of svgalib.

2005-04-20  Stas

	* src/emu-i386/ports.c:
	set_ioperm() should also set the std-handler. This allows the dosemu
	code to call port_outb/port_inb even for the iopermed ports, and the
	real I/O will occur. This is necessary for the mouse gfx code to work
	under X.
	Also disabled HANDLE_VID_IO and HANDLE_SPECIAL. They prevented the
	above code from working and also these features looks completely
	broken and useless.

2005-04-19  Stas

	* src/base/init/: config.c, parser.y.in:

2005-04-17  Stas

	Added the option to control the direct DAC write frequency for OSS.
	No longer need to hack linux_sound.h

	* src/: base/mouse/mouse.c, include/memory.h:
	Moved Mouse_INT_OFF to memory.h and adjusted it instead of changing
	the segment (Stas wake up and stop stumbling around the mouse code!)

	* src/base/mouse/mouse.c:
	Mouse_INT now requires BIOSSEG.

	* src/: env/video/X.c, base/mouse/mouse.c, base/mouse/mouseint.c,
	  plugin/sdl/mouse_SDL.c:
	Enable the native mouse cursor by default (to stay compatible), and
	the X and SDL frontends disable it manually.
	Also "raw" mouse needed the *2 for Y coordinate too. I don't know
	why, maybe the screen resolution is not taken into an account somewhere.

2005-04-16  Stas

	* src/: base/mouse/mouse.c, include/mouse.h:
	Move "native_cursor" to config.mouse, where it actually should be.

	* src/: env/video/X.c, plugin/sdl/mouse_SDL.c:
	X and SDL frontends were erroneously overriding the mouse sensitivity
	values. Also teached X.c about the 2:1 resolution. Native mouse cursor
	now have the proper speed.

	* src/base/mouse/mouse.c:
	Native cursor state should survive save/restore.

	* src/include/memory.h:
	Set 0x33 ivec (mouse) not to 0xf000 segment, as some programs (td)
	are refusing to use it in that case, and the offset should not be 0 too.
	(bug #818094 of myself)

2005-04-15  Stas

	* src/: env/video/X.c, base/mouse/mouse.c, include/mouse.h:

	Disable the selection ability when mouse grab is enabled.

2005-04-14  Stas

	* src/env/video/: X.c, render.c, vbe.c, vga.c:

	* src/env/video/X.c:

2005-04-04  Stas

	* src/env/video/X.c:
	Handle the unlikely case of the miltiple KeyRelease events.

	* src/dosext/dpmi/dpmi.c:
	This keyboard hack is no longer needed.

	* src/env/video/X.c:
	Filter out the fake X KeyRelease events of the autorepeat keyboard mode.
	This fixes bug #1113468, all the recent keyboard regressions, and the
	number of the old keyboard bugs too.
	There are lots of hacks all around dosemu that were trying to work
	around that problem with the different level of success. They all now
	have to be located and removed.

2005-03-26  Stas

	* src/plugin/commands/unix.c:
	Fixes to unix builtin:
	- Dont strip the trailing slashes for the DOS directory path, as this
	path may consist of only that slash (second part of #1152829)
	- Dont terminate if the linux path we wanted to execute, doesn't exist.
	For the DOS path, figuring out the existance is more difficult, so left
	as is for now.

	* src/plugin/commands/builtins.c:
	Small cleanup.

	* src/emu-i386/: cpu.c, ports.c:
	Enlarge line buffer for proc scans, remove smiley ":)" from asm
	constraints (lets put smiles in a comments, not in the code:)

	* src/base/serial/ser_ports.c:
	Update the MSR status before reading it - should make the serial more
	robust.

	* src/base/dev/misc/rtc.c:
	Properly initialize date in cmos. "bios" timesource should now be
	quite usable.

	Also some minor adjustments/leftovers.

2005-03-21  Stas

	* src/base/misc/utilities.c:
	/proc/self/maps can contain lines longer than 100 chars, causing DPMI
	to fail (old bug btw).

	* etc/dosemu.conf:
	0x40000000 for the $_dpmi_base was a bad choise for the non-flexmmap
	kernels. 0x10000000 looks safer.

2005-03-20  Stas

	* src/base/async/int.c:
	Calling io_select() is too expensive, dont do it more than 1000 times
	per second (a cheap fix for the keen4 lockups, but it is still too slow).

	* src/base/mouse/mouse.c:

	* src/: arch/linux/dosext/sound/linux_sound.c,
	  arch/linux/dosext/sound/linux_sound.h, dosext/sound/sound.c,
	  include/sound.h:

	was not confirmed)

	* src/doc/HOWTO/EMUfailure.sgml:
	This was fixed.

	* etc/dosemu.conf:
	Set $_X_aspect_43 to (off), as we agreed, AFAIR.
	This fixes z80s emulator visual artifacts, and many games too.

	* src/base/dev/pic/pic.c:
	Remove the PIC recursion.
	This will probably break everything again, but at least the keyboard
	should survive.

	* src/plugin/kbd_unicode/serv_backend.c:
	Preparing (again) the keyboard code for the removal of the PIC
	recursion. We have to simulate the proper delay between the chars,
	otherwise the nasties races are happening, and whatever is typed,
	gets doubled (bug #1037915).
	Set the emulated kbd clock frequency to 27.5KHz (that is, actually,
	after the set2->set1 translation of 8042; the real frequency may
	be slightly different).
	I hope this is the last implicit dependancy the keyboard code had
	to the PIC code. If all the other subsystems have so many too, then
	we'll be in a big troubles:)

	It turned out that DOS initializes the IVT to not always point to irets.
	If PC-DOS is booted without DOS=HIGH, then for some reasons it sets
	int33 (and others) to some crap, then the crash.
	Besides, this code simply asks for being disabled: the recursion have

	power to dosemu.
	Now we can easily tune the things as per 1.2.1 and better.

	* src/base/serial/ser_ports.c:
	Properly update the buffer counters when receiving data. Horrible
	bug in fact, it used to work by a pure luck before - rx_buffer_slide()
	was bringing the counters in sync at some point, but not always, and
	not any more. This bug was there since the creation of the world.
	This fix whould make the fifo transfers much faster and more reliable.
	Closes #1103434.

	* src/dosext/dpmi/dpmi.c:
	Remove RealModeContext and the surrounding stuff.
	I dont know why it was introduced. It is stated it helps some DJ200
	compiler (djgpp?), but it looks like the hack to work around some
	bugs that are not there any more. If someone know why this stuff
	was necessary, let me know.
	Bart, please see if djgpp feels well now without the hack.

	* src/dosext/dpmi/dpmi.c:
	Made it possible for the 16bit clients to safely access the 32bit API.
	This is not defined in a DPMI specs, so this is a small extension.
	No 16bit client is allowed to use 32bit API, but it is necessary
	for the djgpp-ported API translator to provide the service for 16bit
	clients.

	* src/: include/pci.h, base/dev/misc/pci.c, base/async/pci_bios.c:
	Made pciemu to do something more than just locking up the card
	by fixing the inb/inw.
	Also the header space is enlarged (still reading 64bytes only though).
	Now it works with some cards, but in most cases it still doesnt.
	The cards that reserve an extra PCI ports (like my Radeon) are
	fine, but the ones that dont, usually keep the extended registers
	in the config space, right after the config header. The emulation
	approach cannot fork for them...
	The last argument I've heard against just limiting the direct PCI
	access, was that it would be too slow. But pci_port_inb/pci_port_outb
	already do this!
	I think pciemu have to go away. It is useless, at least for its
	currently intended usage.

	* src/dosext/dpmi/dpmi.c:
	Preserve the high word of ESP across the hw interrupts and exceptions
	for 16bit DPMI clients.
	This fixes the 16bit clients that use the 32bit code with 32bit stack
	sometimes.
	If the 16bit client is interrupted while on 32bit code/stack, it gets
	switched to 16bit stack, where the high word of ESP is lost because of
	the CPU bug. We can save/restore it by hands.
	The 32bit clients that work on 16bit stack are still vulnirable.

	* src/dosext/dpmi/dpmi.c:
	Consolidate the stack switching into enter_lpms()/leave_lpms().

	* src/dosext/dpmi/msdos.c:
	Fixed int33/ax=14h translation (noticed by Japheth)

	* src/dosext/dpmi/dpmi.c:
	Fixed a diabolical bug in do_LAR asm. It was not taking an argument!
	So it operated on whatever random value was in %ax. Sometimes it
	worked because %ax happened to contain the selector, but in most
	cases it just did crap, corrupting the LDT cache. Now z80s emulator
	works (again) and I suppose many other progs do as well.
	This bug was here (presumably) since 1996, and noone noticed?!!!
	This might explain the most of the oddities I observed for years,

	Make sure do_call_back() never executed from within the signal
	context.

	* src/base/async/int.c:
	Disable int33 to DOS callouts. This allows windows to be started
	in enhanced mode by win.com, otherwise crashes.
	The reason is that do_int() can be called from within the signal
	context (by DPMI). Calling realmode code from within the signal
	context is not possible for many reasons (vm86() can emit the signals
	itself, or DPMI may not yet set everything up for realmode code, etc).
	So do_int() must *never* use the do_call_back() variations.

	A DOS mouse driver can now redirect int33; in that case we use NOREVECT

	have to be made.
	Removed the unused indirect function pointer for the mouse callback.
	Enabling the internal driver no longer always sets the int33 vector.
	Implemented a second mouse callback for the PS/2 mouse BIOS.
	All this combined gives a PS/2 mouse bios that actually works so a
	DOS mouse driver (such as CTMOUSE 1.9) can be loaded into xdosemu --

	for ages, at least on 1.0.x it doesnt work).
	- Icons do not disappear from Windows desktop, and winos2 doesnt
	make progman.exe to use system.ini instead of progman.ini (who wrote

	* src/dosext/dpmi/dpmi.c:

	- Check for eIP to not exceed the CS limit (CheckSelectors())
	- When Windows creates the invalid LDT entries, just free the
	entry (type 0). This causes LAR to fail, same as if it would be of
	a type 0x0f, which Windows uses. Bingo!

	This makes get_dir() so much faster (70x) that the sigalrm check is no
	longer necessary.
	Also moved the . and .. in root dir check out of the loop in
	scan_dir.

	* src/dosext/mfs/: lfn.c, mangle.c, mangle.h, mfs.c, util.c:
	Reverted VFAT optimization. It's not reliable for say \`o (o with accent
	grave) where the uppercase equivalent does not exist in CP437. The kernel
	does not uppercase it but DOS and DOSEMU convert it to O. So searching
	for POT where the filename is p\`ot means the expensive way is necessary.
	Introduced a DOS uppercase table to be able to do this quickly, and
	let the LFN code use this. Simplify name_ufs_to_dos to no longer do any
	uppercasing as strupperDOS does this much more quickly. Some cleanups
	in scan_dir to make it more similar to what it was before.

2004-10-16  Bart

	* src/dosext/mfs/mfs.c:
	Simplify last part of loop: the strcasecmp for long and short names could
	be the same thing for a non-mangled name on a non-FAT fs.

	* src/dosext/mfs/: mangle.c, mfs.c:
	Fixed a regression in mangle.c with the unicode->dos table.
	Use the stack instead of malloc in name_convert.
	Only mangle all names in the directory if what we are looking for
	is a mangled name in the first place! Otherwise a simple strcasecmp
	is sufficient. That's another 12x faster for scan_dir(non_mangled_name).
	On VFAT (case insensitive fs) we don't need to scan at all.

	* src/: dosext/mfs/lfn.c, dosext/mfs/mangle.c, dosext/mfs/mfs.c,
	  dosext/mfs/util.c, plugin/translate/translate_config.c,
	  plugin/translate/config/plugin_parser,
	  plugin/translate/include/translate.h:
	Use current locale for the external filename character set (leaving
	keyboard/terminal/paste untouched for now). Allows simply using
	strcasecmp instead of slow unicode compare, and mbsrtowcs for the
	unix->dos filename translation. Gives a further 30% speed improvement
	of readdir searches.

	* src/dosext/mfs/mangle.c:
	Use a 64K-sized char table for unicode->DOS lookups. This makes the
	readdir searches about 3x faster.

	* src/plugin/kbd_unicode/keyb_clients.c:

	Extend $_hardware_ram to allow maps over 1MB with a virtual base that
	DPMI can get. Implement a new set of hardware RAM functions (register,
	map, list, get) and make $_hardware_ram, VGA(PCI), DPMI, and VESA its
	users. A special type (0) is used for virtual mappings (used by VGAEMU);
	otherwise the memcheck character types are used.
	map_hardware_ram tries to map everything that was registered, including
	the low VGA display memory.

	* src/dosext/mfs/mfs.c:
	Speed up scan_dir by uppercasing the name to search for outside the loop
	and only comparing the mangled short name for SFN searches.
	LFN searches only compare the long name case insensitively.
	Use VFAT_IOCTL_READDIR_SHORT on vfat partitions from non-LFN code to
	make sure that LFN's are invisible when they aren't needed.
	Plug memory leak and page fault if you lredir'ed a non-existent
	directory.

	LFB availability is only possible on PCI boards right now.
	If (say) your PCI VGA BIOS only supports VESA 1.2 then it should even be
	possible to load a TSR such as UNIVBE in DOSEMU and the driver will use
	that.

	Provide a way to force reentry into handle_signals() so that we don't
	miss too many SIGALRMs whilst saving the video memory (a thread would
	perhaps be a nicer solution).

	Packet driver networking updates:
	- Use PF_PACKET/SOCK_RAW sockets instead of the deprecated and buggy
	AF_INET/SOCK_PACKET ones, changed the interfaces accordingly.
	- Put the sockets in a bind state - this allows to use the Async IO,
	which makes the direct NIC access mode ~50x faster.
	- Use simple read/write for IO - this is possible with the binded
	RAW sockets (not with the PACKET sockets though - they insist on
	sendto() even when binded, which is a bug).

	* pci_bios.c now registers i/o and memory areas for all PCI devices
	* the real PCI interface can no longer be iopl(3) optimized because
	  of the port server
	* don't allow byte access to port 0xcf9 (can reset the CPU)
	* implemented a read-only PCI emulation interface based on the values

	* use PCI emulation by default with console graphics if PCI is available,

	* allow I/O to all ports that PCI reports about VGA (closes #687024)

	com_dosallocmem()/com_dosfreemem() are no longer necessary.
	Why lowmem_alloc()/lowmem_free() are still there is because the

	- Shuffled the bios.S a bit to get a 32Kb of low memory for free.
	- Added a management for it - lowmem.[ch]. This is needed for VESA

	Fix dozens of memory violations in builtins, mostly detected by the
	smalloc memory allocator. The fixes include (but not limited to the)
	following:
	- Cease the usage of the low mem considerably by calling the helpers
	directly.
	- Protect do_call_back() against re-entering. This was happening
	when eg. cmdline is interrupted by ^C, it was not able to recover.
	- Track all the allocations of load_and_run_DOS_program() to free it
	on termination (leaks).
	- On dos_read()/dos_write() set int0x23 to our return point, so that
	dosemu can recover even in case of ^C.
	- Fix com_strfree() to free the region of a proper size.
	- dos_helper_r is no longer necessary.
	- com_dosread() was not checking the size specified by caller -
	memory corruption.
	- memory corruption with builtin_name, no longer use DOS mem for it.

	- The above is an incompatible change for generic.S. Introduced the
	builtins interface versioning. Now if dosemu detects the outdated
	version of builtins, it will not run them and will ask user to upgrade.
	- Removed the code that was intended to allow calling builtins with
	far call. This code was never used and was broken since generic.S
	started to release memory at startup.
	- Moved DOS version checking from builtins.c to lredir.c.

	* src/base/serial/ser_init.c:
	Unlink the stalled lockfiles for serial and some debug messages cleanup.

	* src/emu.c:
	Remove dummy ign_sigs sighandler for leavedos() - our main sighandler

	Switch the console to cp437 mode only if "linux" is in $TERM and the

	What a mess in fact...
	This cannot be done effectively via mapping system because of the problems
	with uncommitted memory.
	This cannot be done via zalloc because zalloc lacks realloc.
	This patch does:
	- Make pagemalloc to manage multiple pools, and move it to src/base/misc
	- Allocate a memory pool for the committed DPMI allocations and manage it
	with pagemalloc. Uncommitted allocations, even after being committed, are
	still handled separately. This probably cannot be generalized.

	- Timer now works (VTDAPI VxD)

	Note: win32s support is disabled for now - it needs some porting efforts and
	I have lost my test-cases for it.
	Note: Only protected mode entry points are supported. WinOS2 doesnt seem to
	be using the real-mode entry points, so I have not added those.

	It seems Win3.1/WinOS2 works perfectly now as far as I can tell, at least
	similar to how it works under QDPMI.

	Subject: Incorrect bitshifts in instremu.c

	Hi Bart,

	     My fiancee really loves playing her old DOS games
	on DOSEMU, so thanks for the hard work!

	     Running my Scrabble game in DOSEMU, I saw visual
	defects.  After many hours of debugging, I traced the
	problem to instremu.c.

	     My code does "shl al,cl", which should set AL to
	zero when CL is 8.  But DOSEMU treats the 8 as though
	it were a zero.  No x86 CPU behaves this way.

	     According to the MASM reference:

	"On the 80186-80386 processors, shift counts larger than
	31 are masked off, but on the 8088 and 8086, larger shift
	counts are performed despite the inefficiency involved."

	     I experimentated with the other shift and rotate
	commands, and then made a patch to imitate the behavior
	of 80186 and later CPUs.  RCL and RCR are especially
	interesting...
	                                Dave Coffin  6/3/2004

	* src/env/video/X.c:
	Use vga.seq.addr_mode == 2 instead of the number of planes to check for
	chain4 modes of planes. This fixes the Windows logo... #962683

	* src/arch/linux/mapping/mapshm.c:
	For realloc_mapping_shm we can't expand shared anonymous memory using mremap
	so we must allocate a new region and memcpy to it. Fixes a problem with
	WP 5.1's use of EMS

	* src/base/bios/int10.c:
	The int10 BIOS now determines whether a mode is text or graphics from
	the byte at 40:49. Also reduce use of global co and li by peeking these
	values from 40:xx. Eventually co and li should be completely removed.

	* src/env/video/: X.c, vgaemu.c:
	Removed line_compare==0 workaround, since the CRTC init now initializes it
	correctly from the CRTC registers. Have to check at a few places in X.c
	to compensate. This fixes some display problems with bananoid.

	* src/env/video/X.c:
	Fix another scan_len case: fixes problems with resizing zx_emul. Only the
	bars remain.

2004-05-28  Bart

	* src/env/video/X.c:
	Force a redraw for bitmap text modes upon resizing. This helps for plain
	text modes but not for funny text modes such as the one zx_emul uses.

	* src/env/video/X.c:
	Fix hang when non-bitmap fonts were used.

	* src/env/video/: X.c, vgaemu.c:
	Decouple scan_len from co. Sometimes we must use scan_len instead of co...
	Since zx_emul has co=40 but scan_len=48 this is necessary.
	Now zx_emul displays everything correctly except for some annoying vertical bars
	I couldn't get rid off.

	* src/env/video/: X.c, vgaemu.c:
	Correct vgaemu height calculations and relax limits on columns on lines
	(as long as the product*2 is within 64k)

	* src/env/video/: X.c, seqemu.c, vgaemu.c:
	Respect sequencer for determining 8- or 9- pixel wide characters.
	X_update_text_screen should respect a changed display and resize.

	* src/: base/bios/int10.c, env/video/vgaemu.c:
	Text modes in X now update from the aliased memory (high up in the Linux
	address space), instead of 0xa0000-0xc0000; will be necessary to use
	instremu for text modes. Corrected one related screen_adr assignment.

	* src/dosext/dpmi/dpmi.c:
	Use syscall() for modify_ldt. Not sure if this fixes the Fedora problem yet
	but it is consistent with the other syscalls anyway.

	* src/: base/serial/ser_ports.c, arch/linux/async/sigsegv.c,
	dosext/dpmi/dpmi.c, dosext/dpmi/memory.c, include/Linux/serial.h:

	src/base/bios/Makefile, src/env/video/Makefile:
	Don't use CFLAGS for the 16bit BIOS asm files. The -g in there confused
	binutils/gdb and that was the reason for the -gstabs+. Now we can just
	use the standard dwarf-2 debug info in dosemu.
	Also default-configure must check for gpm, not libgpm in compiletime-settings.

	* etc/global.conf:
	Remove warning that wasn't any more ...

	Correct new problem with $_chipset

2004-05-07  Bart

	* src/arch/linux/async/: Makefile, debug.c, debug.h, signal.c,

	Added Stas' auto-gdb patch. I changed two small things: avoid buf[255]
	(potential buffer overflow), and also output what "ldd" says.
	getconf GNU_LIBC_VERSION must be quite recent (GLIBC 2.3+ I think) by
	the way, doesn't work here with 2.2.4
	getconf: Unrecognised variable `GNU_LIBC_VERSION'
	That doesn't hurt though.

	* etc/global.conf, src/base/init/parser.y.in:
	Limit use of strlen in global.conf; move com port processing into a loop.
	For some reason foreach doesn't always play nicely with if :(
	Don't define a serial port in the parser with an empty device ("virtual"
	still works though)
	Please check if this doesn't break your favourite configuration.

	* src/: emu-i386/do_vm86.c, include/cpu.h:
	Avoid more deprecated casts. Not sure if prefix66 ^ prefix67 is the right
	thing for ecx... Have to look that up.

	* src/emu-i386/cpu.c:
	Fixed GCC 3.3.3 warning:
	cpu.c:154: warning: use of conditional expressions as lvalues is deprecated
	cpu.c:154: warning: use of cast expressions as lvalues is deprecated

	* src/emu-i386/cputime.c:
	Don't zero trigger1 after usleep.

2004-05-02  Bart

	* src/: base/async/int.c, base/bios/int16.c, emu-i386/cputime.c,
	include/timers.h:
	Consolidated all idling calls that use a trigger into one common function
	with a common trigger. All triggers now reset after each usleep(). Also
	the MFS resets the trigger. There may be more places where that is useful.

	* src/env/video/: X.c, remap.c:
	reconfig.mem should become 0 again after redrawing the text screen.
	fixed an x-offset bug in remap.c: now X.c can properly draw rectangles of
	texts, and not just screen-wide blocks.
	The combination of these two changes makes bitmap fonts much faster.

2004-05-01  Bart

	* src/arch/linux/mapping/mapshm.c:
	From Stas: use MAP_SHARED | MAP_ANONYMOUS instead of IPC.

2004-04-30  Bart

	- Map lowmem instead of unmapping KMEM - this makes the interfaces more
	consistent.

	* src/env/video/: vc.c, vga.c:
	Fix a couple of small new bugs encountered in the cleaned up video code.

2004-04-11  Bart

	* src/: arch/linux/mapping/mapping.c, env/video/vc.c,
	include/mapping.h:
	Mostly from Stas: use COPYBACK cap to avoid a temporary buffer when
	flipping between /dev/mem memory and low memory.
	Bart: clean up a bit, use size_t instead of off_t (off_t is a signed
	type used for file offsets!) and remove the root checks (if extended
	mremap is available).

	* src/: include/vc.h, env/video/console.c, env/video/vc.c,
	env/video/vga.c, env/video/video.c:
	Clean up vc get/put video ram routines. It should now be clear how and
	where to apply Stas' patch.

	* src/: emu.c, env/video/X.c, include/video.h,
	plugin/term/terminal.c, env/video/console.c, env/video/dualmon.c,
	env/video/hgc.c, env/video/video.c:
	Introduced a priv_init field for the video system. priv_init (for now) calls
	the old console driver init procedure. init calls the console driver
	post_init and for the terminal and X the normal init. Hopefully this doesn't
	break too much -- terminal and X still work.

2004-04-08  Bart

	* src/dosext/mfs/lfn.c:
	Implemented our own LFN filematch routine, with a little help from
	GLIBC. Special trick is to add a period if it's not there so that:
	dir *.
	matches all files without an extension.
	log and log? match log (==log.), but log?? doesn't match.

	* src/dosext/mfs/lfn.c:
	LFN: wildcard delete and findfirst/next need to match both sfn's and lfn's!
	-- in Win98 "dir *1.*" will give you almost all LFNs.
	Next stage will be to dumb down fnmatch with a custom version.

	Dont allow client stack to run above the dosemu stack. This is a loosy
	attempt to work around a ESP CPU bug. Seems to get the ancient MS linker
	to work. (bug #929123)

	* src/include/emu.h:
	linux-2.6 needs SA_NODEFER to allow the recursive signal handling. We need
	2 nesting levels of SIGSEGV sometimes. (part of bug #929123)

	dosext/dpmi/msdos.c, dosext/dpmi/msdos.h, include/doshelpers.h,
	include/int.h, include/memory.h:
	- Added wrappers for DOS I/O (int21/ah=0x3f,0x40) to allow read/write >64K.
	- Added helpers to pass data between the high and low mem.
	- PM API Translator adjusted to use the new wrappers for I/O operations.
	- READ_DS_COPIED no longer needed, removed.
	This patch allows 32rtm to work. This is a noticeable step - 32rtm allows
	to run win32 console apps (PE).
	Many thanks to japheth@users.sourceforge.net for locating so many problems
	and providing a usefull hints.

2004-03-30  Bart

	* src/: dosext/mfs/lfn.c, dosext/mfs/mfs.c, dosext/mfs/util.c,

2004-03-29  Stas

	* src/dosext/dpmi/memory.c:
	Always map the uncommitted mem to zeropage.

	* src/: arch/linux/mapping/mapping.c, base/init/init.c:
	- kmem_map_mapping() was necessary only to supply the lowmem hack.
	Since there is nomore a hack, kmem_map_mapping() is unnecessary.
	- add missing alloc_mapping() call.

2004-03-29  Bart

	* src/: emu.c, arch/linux/mapping/mapping.c, env/video/console.c,
	env/video/vc.c, env/video/vga.c, env/video/video.c, include/emu.h,
	include/video.h:
	Introduced video_post_init(): mmaps /dev/mem for video RAM and
	sets up VC switch functionality.  This allows for the complete
	removal of the mapping.c hacks.

	* src/: emu.c, arch/linux/mapping/mapping.c, base/dev/misc/lpt.c,

	emu-i386/ports.c, env/video/X.c, env/video/console.c,
	env/video/vc.c, env/video/video.c, include/emu.h, include/mouse.h:
	Seperate low memory initialization from the rest of the init and fixed
	a few NULL pointer dereferences...
	Note: this allows us to remove some hacks but by keeping a temporary
	fd to /dev/mem open during init we will also be able to mmap video
	ram after dropping privs, so more can be removed in mapping.c...
	Dropping privs can then be done much earlier, and also is independent
	from memory mapping.
	* printer: set BIOS values in printer_mem_setup()
	* video: set BIOS values in video_mem_setup()
	* dev_list: add mouse_reset and serial_reset handlers which just like
	  the keyboard reset handler fill in the BIOS values.
	* call the reset handler just before booting, not immediately after
	  the init handler
	* move the mouse_reset_to_current_video_mode() during init to
	  mouse_post_boot() (current_video_mode may be strange for fbdev now,
	  was 0....)
	* mouse.c: fixed sptr null dereference
	* mouseint.c: fixed mice->dev NULL deref
	* cputime.c: Video may be NULL for first console switches at init while
	  console code is playing with ioctls
	* ports.c -- can derive BIOS_VIDEO_PORT value from dosemu config
	* X.c check for config.X_font being NULL
	* removed a few superfluous calls to clear_screen() and set_video_bios_size()
	* vc.c: can't read the BIOS during the first get_video_ram and console
	  switch --- this really needs to be cleaned up...

2004-03-28  Stas

	* src/arch/linux/mapping/mapping.c:

	Next chunk of Stas' changes -- this one doesn't really do anything
	except for limiting the size of the patch I want to have a closer
	look at.

	* src/arch/linux/mapping/mapping.c:
	The basic changes need this one too, or DOSEMU is completely broken ...

	src/base/misc/hma.c, src/dosext/dpmi/memory.c,
	src/dosext/misc/emm.c, src/include/mapping.h,
	src/include/Linux/mman.h:

	Remove "console" from global.conf for $_graphics=(1) since it already
	implies "console" in the parser anyway.

2004-03-16  Bart

	* Makefile.conf.in, src/commands/Makefile,
	src/arch/linux/Makefile.main:
	Define LD at the right place. Remove unnecessary exports in
	Makefile.main

2004-03-13  Stas

	* src/dosext/dpmi/msdos.c:
	Fix bug in function 0x56 (rename file), from #909015
	Properly return the canonicalized filename to DPMI client
	(from bug #909015)

	* src/dosext/dpmi/: dpmi.c, memory.c:
	Escaped bits from previous commit (use RWX, not RW).

2004-03-12  Bart

	* configure:
	autoconf

2004-03-11  Bart

	* VERSION:
	Bump up VERSION in CVS already so people won't confuse it with 
	1.3.0 from the tarball.

2004-03-11  Stas

	* configure.ac:
	More escaped bits from the mapping redesign commit.

	* src/base/misc/: dosio.c, shared.c:
	Escaped bits from the mapping redesign commit.

	* src/: arch/linux/mapping/mapping.c, base/init/init.c,
	include/mapping.h:
	Had to create an even bigger hack because the aliased low memory now
	overwrites any /dev/mem areas -- this broke console graphics.
	So we have to be careful to see which areas were already mapped to
	/dev/mem (using a char array that check if a page is /dev/mem or not)
	Hopefully with this working base I can start cleaning things up.

2004-03-10  Bart

	* src/dosext/dpmi/memory.c:
	Need to include "emu.h" before other headers to get config.h including
	_GNU_SOURCE...
	See /usr/include/features.h
	#ifdef  _GNU_SOURCE
	# define __USE_GNU      1
	#endif
	_GNU_SOURCE is documented. __USE_GNU is internal to Glibc (AFAICS)

	* src/: arch/linux/mapping/mapping.c, arch/linux/mapping/mapshm.c,
	dosext/dpmi/memory.c, dosext/sound/sound.c,
	arch/linux/dosext/sound/midid/midid.c, base/dev/dma/dma.c:
	- Use RWX permissions for IPC SHM by default instead of RW,
	otherwise we end up with the non-executable first meg (but it
	didnt hurt since on x86 it is possible to execute regardless).
	- Update my e-mail address :)

2004-03-08  Stas

	* src/: emu-i386/do_vm86.c, include/emu.h,
	plugin/commands/builtins.c:
	Alowing interrupts during the callbacks proved to be reliable, making a
	default.

	* src/plugin/commands/comcom.h, src/plugin/commands/commands.c:
	Remove the remaining traces of comcom.

2004-03-07  Stas

	* src/dosext/dpmi/: dpmi.c, dpmi.h, msdos.c:
	Properly free segregs after freeing memory block (from bug #909015)

2004-03-07  Bart

	* src/: emu.c, arch/linux/mapping/mapfile.c,
	arch/linux/mapping/mapping.c, arch/linux/mapping/mapshm.c,
	emu-i386/ports.c, emu-i386/simx86/memory.c, include/mapping.h,
	include/vm86plus.h:
	Removed direct kernel interfaces where possible and replaced inline asm
	by syscall() otherwise -- the latter allows glibc to use sysenter and
	friends.
	The calls for syscall() are extended_mremap, dosemu_sigaction,
	vm86_old and vm86_plus. Note however that dosemu_sigaction is only
	called when sigaltstack is not supported.

2004-03-07  Stas

	* src/: base/bios/bios.S, dosext/dpmi/dpmi.c, include/bios.h:
	- Implemented extended exception stack frame (DPMI 1.0, needed by rtm32)
	- Allow Visible Page Faults (DPMI 1.0, needed by bug #909015 and rtm32)

	* src/: arch/linux/mapping/mapping.c, dosext/misc/emm.c,
	include/mapping.h:
	Update EMM to new mapping flag.

2004-03-07  Bart

	* src/: base/misc/disks.c, base/misc/utilities.c, include/disks.h,
	include/utilities.h, tools/periph/hdinfo.c:
	eliminate libless_llseek. For hdinfo we can use _FILE_OFFSET_BITS==64
	as it's standalone. For disks.c it's safer to explicitly use *64 calls.
	#ifdef __linux__ is a little optimistic but doesn't hurt :)

	include/emu.h, include/mapping.h, include/memory.h:
	Mapping system revamp.
	- Added support for lowmem region, it is now a part of SHM segment.
	- Moved DPMI memory away from SHM segment.
	- Updated HMA, DPMI and other subsystems to the new mapping features.

	* src/dosext/dpmi/: dpmi.c, dpmi.h, msdos.c:
	Next part of bug #902742:
	- remaining issues with is_dos_selector() fixed.
	- couple of 16/32bit registers confusion fixed.
	dos_read/dos_write case is not yet.

2004-03-06  Stas

	* src/dosext/dpmi/: dpmi.c, dpmi.h, msdos.c:
	Allocate 6 realmode stacks for each DPMI client instead of 16 for 
	all clients. Blinker extender is now supported (closes SR #855611).
