# Makefile for mdate
# $Id$
#
# Usage:
#	make target=linux					# linux
#	make target=cygwin					# cygwin 1.3.x
#	make target=mingw64-cross mdate.exe	# linux (Debian) win32 cross-compile
#	gmake target=freebsd				# FreeBSD 4.x target
#	make target=beos					# BeOS r5
#	make target=osx						# Mac OSX 32-bit console
#
# The default target is linux on x86 with a pentium-class processor.
# I can't guarantee the other targets will work, I haven't used Cygwin for
# quite a while now, it's probably out of date. Fixes would be most welcome.
#
# I use the default 32bit target for mingw64 at present. If there is need I
# can provide a 64bit target also.
#
# If the CFLAGS bother you, please dont change -ffloat-store which avoids
# architecture-related problems.
#
# If you want to add a needed target for your OS/distribution, go ahead but
# please email me (Sean Dwyer <ewe2@users.sourceforge.net>) and include a
# patch of your changes so everyone can share!
#
# You may also want to check the documentation targets if you don't need some
# formats: grep for createdoc.
#
# Installation targets may need to be defined for your platform, see the freebsd
# target for an example.
