text: # Makefile for zlib under OS/2 using GCC (PGCC)
  # For conditions of distribution and use, see copyright notice in zlib.h
  
  # To compile and test, type:
  #   cp Makefile.os2 ..
  #   cd ..
  #   make -f Makefile.os2 test
  
  # This makefile will build a static library z.lib, a shared library
  # z.dll and a import library zdll.lib. You can use either z.lib or
  # zdll.lib by specifying either -lz or -lzdll on gcc's command line
  
  CC=gcc -Zomf -s
  
  CFLAGS=-O6 -Wall
  #CFLAGS=-O -DMAX_WBITS=14 -DMAX_MEM_LEVEL=7
  #CFLAGS=-g -DDEBUG
  #CFLAGS=-O3 -Wall -Wwrite-strings -Wpointer-arith -Wconversion \
  #           -Wstrict-prototypes -Wmissing-prototypes
  
  #################### BUG WARNING: #####################
  ## infcodes.c hits a bug in pgcc-1.0, so you have to use either
  ## -O# where # <= 4 or one of (-fno-ommit-frame-pointer or -fno-force-mem)
  ## This bug is reportedly fixed in pgcc >1.0, but this was not tested
  CFLAGS+=-fno-force-mem
