# WMAKE makefile for Windows 95 and Windows NT (Intel only)
# using Watcom C/C++ v11.0+, by Paul Kienitz, last revised 29 Sep 97.
# Makes UnZip.exe, fUnZip.exe, and UnZipSFX.exe.
#
# Invoke from UnZip source dir with "WMAKE -F WIN32\MAKEFILE.WAT [targets]"
# To build with debug info use "WMAKE DEBUG=1 ..."
# To build with no assembly modules use "WMAKE NOASM=1 ..."
# To support unshrinking and unreducing use "WMAKE LAWSUIT=1 ..."
#
# Other options to be fed to the compiler can be specified in an environment
# variable called LOCAL_UNZIP.
