-#==============================================================================
-# Makefile for UnZip, UnZipSFX and fUnZip: Unix and MS-DOS ("real" makes only)
-# Version: 5.52 04 Feb 2005
-#==============================================================================
-
-
-# INSTRUCTIONS (such as they are):
-#
-# "make sunos" -- makes UnZip in current directory on a generic SunOS 4.x Sun
-# "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 that 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 fileio.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.
