# this makefile in OW WMake style creates JWasm.EXE (Win32) and optionally
# JWasmD.EXE (DOS).
# tools used:
# - Open Watcom v1.9
# - jwlink ( optionally OW Wlink may be used, see below )
# - HXDev  ( needed only if a DOS version is to be created )
#
# "WMake"         - creates the Win32 version.
# "WMake debug=1" - creates the Win32 debug version.
# "WMake dos=1"   - creates both Win32 and DOS version (JWasmD.exe)
# "WMake djgpp=1" - creates a Win32 version with DJGPP support.
# "WMake wlink=1" - create a Win32 version that is linked with OW Wlink.
