# WMAKE makefile for 16 bit MSDOS or 32 bit DOS extender (PMODE/W or DOS/4GW)
# using Watcom C/C++ v11.0+, by Paul Kienitz, last revised 16 Feb 2008.
# Makes UnZip.exe, fUnZip.exe, and UnZipSFX.exe.
#
# Invoke from UnZip source dir with "WMAKE -F MSDOS\MAKEFILE.WAT [targets]".
# To make the PMODE/W version use "WMAKE PM=1 ..."
# To make the DOS/4GW version use "WMAKE GW=1 ..." (overrides PM=1)
# Note: specifying PM or GW without NOASM requires that the win32 source
# directory be present, so it can access the 32 bit assembly source.
# PMODE/W is recommended over DOS/4GW for best performance.
# To build with debug info use "WMAKE DEBUG=1 ..."
# To build with no assembly modules use "WMAKE NOASM=1 ..."
# To omit unshrinking support use "WMAKE NO_LZW=1 ..."
# To support unreducing, get the real unreduce.c and go "WMAKE OFFEND_RMS=1 ..."
# To include support for bzip2 decompression (only for 32-bit), get the bzip2
# source distribution into the bzip2/ subfolder and start compilation
# with "WMAKE PM=1 USEBZ2=1 ..."
#
# Other options to be fed to the compiler can be specified in an environment
# variable called LOCAL_UNZIP.
