# ===========================================================================
# Makefile for UnZip, ZipInfo & Ship:  Unix, OS/2 and MS-DOS (MSC NMAKE only)
# Version:  decrypt + (conditionally) inflate
# ===========================================================================
#
#
# INSTRUCTIONS (such as they are):
#
# "make vax"	-- makes UnZip on a VAX 11-780 BSD 4.3 in current directory
#		   (or a SysV VAX, or an 8600 running Ultrix, or...)
# "make"	-- uses environment variable SYSTEM to set the type
#		   system to compile for.  This doesn't work for some
#		   particularly brain-damaged versions of make (VAX BSD,
#		   Gould, and SCO Unix are in this group).  If SYSTEM not
#		   set, gives instructions on what to try instead.
# "make list"	-- lists all supported systems (targets), including ship
#		   and zipinfo targets
# "make wombat" -- Chokes and dies if you haven't added the specifics
#		   for your Wombat 68000 (or whatever) to the systems list.
#
# CFLAGS are flags for the C compiler.  LDFLAGS are flags for the loader.
# LDFLAGS2 are more flags for the loader, if they need to be at the end of
# the line instead of at the beginning.
#
# My host (a VAX 11-780 running BSD 4.3) is hereafter referred to as "my host."
#
# My host's /usr/include/sys/param.h defines BSD for me.  You may have to add
# "-DBSD" to the list of CFLAGS for your system.
#
# Some versions of make do not define the macro "$(MAKE)" (my host did not).
# The makefile should now handle such systems correctly, more or less; the
# possible exception to this is if you've used a make command-line option
# (for example, the one which displays the commands which WOULD be executed,
# but doesn't actually execute them).  It probably needs some more tinkering.
# If things still don't work, use "make" instead of "$(MAKE)" in your system's
# makerule.  Or try adding the following line to your .login file:
#   setenv MAKE "make"
# (It didn't help on my host.)
#
# memcpy and memset are provided for those systems that don't have them;
# they're found in misc.c and will be used if -DZMEM is included in the list
# of CFLAGS.  These days ALMOST all systems have them (they're mandated by
# ANSI), but older systems might be lacking.  And at least ONE machine's
# version results in some serious performance degradation...
#
# SCO Unix 3.2.0:  Don't use -Ox with cc (derived from Microsoft 5.1); there
# is a bug in the loop optimization which causes bad CRC's.  [Onno van der
# Linden]
#
# Be sure to test your nice new UnZip; successful compilation does not always
# imply a working program.

# DEFAULT HANDLING #
####################

# The below will try to use your shell variable "SYSTEM" as the type system
# to use (e.g., if you type "make" with no parameters at the command line).
# The test for $(MAKE) is necessary for VAX BSD make (and Gould, apparently),
# as is the "goober" (else stupid makes see an "else ;" statement, which they
# don't like).  "goober" must then be made into a valid target for machines
# which DO define MAKE properly (and have SYSTEM set).  Quel kluge, non?
# And to top it all off, it appears that the VAX, at least, can't pick SYSTEM
# out of the environment either (which, I suppose, should not be surprising).
# [Btw, if the empty "goober" target causes someone else's make to barf, just
# add an "@echo > /dev/null" command (or whatever).  Works OK on the Amdahl
# and Crays, though.]

# Enclosed you'll find a context diff for the unzip41 makefile
# which enhances compilation on a convex.  The previous version
# probably worked great a couple of years ago, and would still do
# so if one compiles in our "backward compatible" pcc mode.   The
# following allows it to work better in a modern convexian environment
# (define __STDC__ manually because default compilation mode has
# extensions and thus doesn't do so).  [5 Mar 1992:  -D__STDC__ removed
# for now because of problems with stat.h]
