# Makefile for Info-ZIP's UnZip, UnZipSFX and fUnZip using djgpp v2.01, by
# Frank Donahoe. Last updated: 30 Sept 97
# This Makefile is specifically tailored for GNU make and GNU C and
# may not work with a generic Unix-compatible make utility. The latest
# make version is 3.75. Thanks to Eli Zaretskii for generously responding
# to questions with advice on the changes needed to make install work under
# the new version.
# Features used:
# - pattern rules (%.o : %.c, etc.)
# - GNU-specific conditionals and functions (ifeq, $(patsubst,,),...)
#
# The stand-alone executable requires DPMI services to run. If running
# in a DOS window under Windows 3.1 or later, the dpmi server is auto-
# matically present. Under DOS, if a DPMI server is not loaded, the
# program will look for "cwsdpmi.exe." If found, it will be loaded for
# the duration of the program.
#
# cwsdpmi is a "free" dpmi server written by Charles W. Sandmann
# (sandman@clio.rice.edu). It may be found, among other sites, on SimTel
# Net at the URL:
#
# ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2misc/csdpmi?[b,s].zip
#
# and on its mirrors worldwide. The latest version as of this writing is 3.
# Archives with the b postscript contain the binaries. An alternate server
# is found, l.c., in the archive pmode??[b,s].zip. The latest (960908) is
# v1.1.
# Separators colon and <sp> are used in Unix, semi-colon and <sp> in DOS.

# LOCAL_UNZIP=-DDOSWILD
# BUTT=-m486
# BUTT may also be defined to specify the target system. At present, -m386
# and -m486 are the only supported options. Either will produce code that
# will run on the other microprocessor, though possibly not so fast.
# In any case, omitting BUTT will result in a slightly smaller executable.

# executable files will be converted to self-extracting compressed files.
