# Makefile for UnZip(SFX) and fUnZip for Borland C++ 2.x-4.x and Turbo C++ 1.0
# Version: 5.5 and later         Alvin Koh, Jim Knoble, Christian Spieler, etc.
#
# Last revised:  04 Mar 01
#
# To compile with Turbo C++ 1.0, set the macro CC_REV to 1 at the command line
# (make -fmsdos/makefile.bc -DCC_REV=1).


#    GNU make doesn't like the return value from "rem"
#STRIP=rem
STRIP=echo  Ignore this line.
#    If you don't have UPX, LZEXE, or PKLITE, get one of them. Then define:
#    (NOTE: upx needs a 386 or higher system to run the exe compressor)
#STRIP=upx --8086 --best
#    or
#STRIP=lzexe
#    or
#STRIP=pklite
#    This makes a big difference in .exe size (and possibly load time).


#    Optional nonstandard preprocessor flags (as -DCHECK_EOF or -DDOS_WILD)
#    should be added to the environment via "set LOCAL_UNZIP=-DFOO" or added
#    to the declaration of LOC here:
LOC = $(LOCAL_UNZIP)

# Type for CPU required: 0: 8086, 1: 80186, 2: 80286, 3: 80386, etc.
CPU_TYP = 0

# "near data" model is sufficient for UnZip and ZipInfo, now that strings moved
# switched to medium model; UnZip code has grown beyond the 64k limit.
# since 5.42: switched to large model; medium model requires to much memory
# to compile zipinfo, reported for BC++ 4.51 and TC++ 1.0
# (compilation worked with 624k DOS memory and TC++ 1.0, but that much free
# space requires an almost "empty" DOS system)
