# Makefile for Info-ZIP's UnZip, UnZipSFX and fUnZip using DJGPP v2.01 or

# higher, by Frank Donahoe.                      Last updated: 21 Jul 2008

# 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 3.78.1.  Thanks to Eli Zaretskii for generously responding

# to questions with advice on the changes needed to make install work under

# DJGPP version 2.0x.

# Features used:

# - pattern rules (%.o : %.c, etc.)

# - GNU-specific conditionals and functions  (ifeq, $(patsubst,,),...)

# - simply expanded variables (VAR := text)

#

# 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 5.

# Archives with the b postscript contain the binaries.  An alternate server

# is found, l.c., in the archive pmode??[b,s].zip.  The latest (20001022) is

# v1.3.

# Separators colon and  are used in Unix, semi-colon and  in DOS.

# UnZip flags

# LOCAL_UNZIP may be set in "AUTOEXEC.BAT" or defined in "djgpp.env" under

# [make] as in the example below.  Or, if you habitually work in a DOS box

# under Windows9x, right click on the MS-DOS icon, select properties, then

# program, to find a slot called batch file, where you may specify the path

# to a file which will set the variables of choice every time the box is

# opened.

# See, for example, DOSWILD, in the file INSTALL.

# [make]

# +BUTT=-mcpu=pentiumpro

# +LOC=-W -Wall

# +LOCAL_UNZIP=-DUSE_UNSHRINK

# BUTT may be defined to specify the target system.  With gcc v2.95,

# optimizing options like "-mcpu=pentiumpro -march=pentiumpro" are supported,

# but the traditional "-m386" and "-m486" options of previous gcc 2.x

# version will continue to work.

# So if you are in the habit of compiling from source, programs for your

# own use, it is well to consult gcc's manual for options suitable to

# your processer and to set BUTT accordingly.  Consult INSTALL for

# LOCAL_UNZIP.
