# Makefile for zlib
# Microsoft C 5.1 or later

# To use, do "make makefile.msc"
# To compile in small model, set below: MODEL=S

# If you wish to reduce the memory requirements (default 256K for big
# objects plus a few K), you can add to the LOC macro below:
#   -DMAX_MEM_LEVEL=7 -DMAX_WBITS=14
# See zconf.h for details about the memory requirements.

# ------------- Microsoft C 5.1 and later -------------

#    Optional nonstandard preprocessor flags (e.g. -DMAX_MEM_LEVEL=7)
#    should be added to the environment via "set LOCAL_ZLIB=-DFOO" or added
#    to the declaration of LOC here:
LOC = $(LOCAL_ZLIB)

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

# Memory model: one of S, M, C, L (small, medium, compact, large)
MODEL=L

CC=cl
CFLAGS=-nologo -A$(MODEL) -G$(CPU_TYP) -W3 -Oait -Gs $(LOC)
#-Ox generates bad code with MSC 5.1
LIB_CFLAGS=-Zl $(CFLAGS)

LD=link
LDFLAGS=/noi/e/st:0x1500/noe/farcall/packcode
# "/farcall/packcode" are only useful for `large code' memory models
# but should be a "no-op" for small code models.
