# Makefile for UnZip, UnZipSFX and fUnZip:  Unix and MS-DOS ("real" makes only)
# Version:  5.12                                                 25 August 1994
#==============================================================================


# INSTRUCTIONS (such as they are):
#
# "make vax"	-- makes UnZip on a generic Unix VAX in the current directory
# "make list"	-- lists all supported systems (targets)
# "make help"	-- provides pointers on what targets to try if problems occur
# "make wombat" -- chokes and dies if you haven't added the specifics for your
#		    Wombat 68000 (or whatever) to the systems list
#
# CF are flags for the C compiler.  LF are flags for the loader.  LF2 are more
# flags for the loader, if they need to be at the end of the line instead of at
# the beginning (for example, some libraries).  FL and FL2 are the corre-
# sponding flags for fUnZip.  LOCAL_UNZIP is an environment variable that can
# be used to add default C flags to your compile without editing the Makefile
# (e.g., -DDEBUG_STRUC, or -FPi87 on PCs using Microsoft C).
#
# Some versions of make do not define the macro "$(MAKE)"; this is rare, but
# if things don't work, try using "make" instead of "$(MAKE)" in your system's
# makerule.  Or try adding the following line to your .login file:
#	setenv MAKE "make"
# (That never works--makes which are too stupid to define MAKE are also too
# stupid to look in the environment--but try it anyway for kicks. :-) )
#
# Memcpy and memset are provided for those systems that don't have them; they
# are in file_io.c and will be used if -DZMEM is included in CF.  These days
# almost all systems have them.
#
# Be sure to test your new UnZip (and UnZipSFX and fUnZip); successful compila-
# tion does not always imply a working program.
