Changelog:

  • fix: Check for Win64 in Watcom makefile via %ProgramFiles(x86) (Bart)
    chg: Build xms-swap by default (Bart)
  • fix: Use -fno-builtin for GCC to use libc/overridden functions everywhere (Bart)
  • chg: Use -mregparmcall for GCC. Needs adjustment of intr() prototype
    (still stdcall) (Bart)
  • chg: Add linker script command.ld so relocations can be used in NASM code
    for GCC via _TEXTSEG. (Bart)
  • fix: Force 8086-asm; use direct call far real_XMSexec instead of push/push/retf.
    Fixes #15 (Bart)
  • fix: Move termination hook into seperate file and always use independent of XMS.
    Closes #16 (Bart)
  • fix: Fix loadhigh failure when zero-byte free memory block is exist
    (Sava, lpproj)
  • fix: Allow escape of > < | via ^> ^< and ^|. Fixes #12. (Bart)
  • fix: Fix build break on msys2 (with *-mingw32-gcc and ia16-elf-gcc)
    (Sava,lpproj)
  • fix: LH/LOADFIX call execute instead of exec and skip bat files. Fixes #8.
    (Bart)
  • fix: LOADFIX: stop manipulating UMB link, use first fit>0x10000. Fixes #10.
    (Bart)
  • fix: dosGetUMBLinkState needs to return state in _AL, not _AX (see #10)
    (Bart)
  • fix: Avoid possible NULL dereference in dprintf. Fixes #9 (Bart)
  • fix: XMScopy needs to be declared noinline for GCC to work correctly. (Bart)
  • fix: Fix "copy con file" where file already exists. (Bart)
    We need to use devopen instead of dfnstat to check for src existence.
  • fix: Create and use sfn_creat() for dos_creatnew() redone.
    Also rename dos_creatnew() to sfn_creatnew().
    Using creat instead of creatnew for file creation avoids
    the need for truncation using write(), and the handle can
    be directly used without needing to reopen the file.
    However, differently from the previous try, LFNs are still reopened for
    compatibility with Windows 2000/XP. (Bart)
  • fix: dos_read and dos_write now call farread/write for all compilers.
    This is more consistent and fixes truncating writes for GCC. (Bart)
  • fix: Fix lfnmkdir to really create LFNs; easiest to separate out. (Bart)
  • fix: Don't use expensive open/close to check for SFN.
    Instead use the boolean, then put in extra check to see if
    int21/ax=7160 works. (Bart)
  • fix: Add stack checking, adapted from Tom Ehlert (Bart)
  • fix: Save another 520 bytes of stack by reusing buffers where safe. (Bart)
  • fix: myfnsplit(): use common buffer to store dir/name/ext to save stack space.
    This saves ~1250 bytes of stack and eliminates stack overflows in the
    ke2041 test in metados. (Bart)
  • chg: Generate 28.com and 50.com from assembly language. (Bart)
