# this makefile creates the 32bit OS/2 binary of JWasm.
# tools used:
# - Open Watcom v1.8/v1.9

# Note that this makefile assumes that the OW environment is
# set - the OW tools are to be found in the PATH and the INCLUDE
# environment variable is set correctly.

# 2011-07-09 -- rousseau at ecomstation.com -- fixed some stuff.
# - Removed a trailing space after the '&' in the object-list on the
#   line with '$(OUTD)/omffixup.obj' that breaks wmake v1.9.
# - Added '.SYMBOLIC' to 'clean:' to supress dependency checking.
# - Added check for existence of files to 'clean:' to supress
#   abort when files are not found.
# - Replaced 'erase' with 'del' in 'clean:' as this is the more common name.
