All 24 source files compile and link for DOS/4GW 32-bit target using OpenWatcom V2 cross-compiler (wcc386 -bt=dos -mf -za99 -D__MSDOS__). Platform portability fixes: - hal_dos.c: use int386() instead of int86() for 32-bit DOS - interp.c: mkdir() 1-arg on DOS, _dos_findfirst/findnext for FILES, monotonic_time() portable wrapper for clock_gettime/clock() - virmem.c: replace clock_gettime with portable time()/localtime() - graphics.c: define M_PI, avoid non-constant aggregate initializers - tui.c: guard sys/ioctl.h and sigaction, use signal() on DOS, use HAL screen size instead of TIOCGWINSZ Produces: gwbasic.exe (154KB LE executable, requires DOS4GW.EXE) Linux build and all 72+14+69 tests unaffected.

# Usage:
|
|
# wmake -f Makefile.dos (from OpenWatcom environment)
