# Makefile for Info-ZIP's unzip, zipinfo, funzip and unzipsfx
# using djgpp v1.12m4. Tested with unzip550 by Christian Spieler
#
# This Makefile is specifically tailored for GNU Make and GNU C and
# may not work with a generic UNIX compatible Make utility.
# Features use:
# - pattern rules (%.o : %.c, etc.)
# - GNUMake conditionals and functions (ifeq, $(patsubst,,),...)
#
# To allow mixed use of real mode (16bit) vs. GO32 (32bit protected mode)
# GNUMake utility and GCC driver, precautions have been taken to
# limit command lines to the DOS 126 bytes limit.
# In case you have an environment that supports long command lines
# at all "interface" levels (e.g.: DJGPPv1 Gmake 3.71 and GO32 gcc.exe),
# you may define the Makefile macro LONGARGS to take advantage of the
# "long command lines" capability.
# I have archived the fastest compilation (with LONGARGS support!) by
# using both a real mode gnumake (private port) and the real mode
# gcc.exe driver.
#
# The Makefile allows the optional creation of standalone exectutables.
# This has the advantage that unzip.exe does not rely on any other file,
# but results in much larger executables.
#
# Separators colon and <sp> are used in U**X, semi-colon and <sp> in DOS.
