# Makefile for Info-ZIP's unzip, unzipsfx, and funzip on BeOS
#
# Copyright (c) 1998 Info-ZIP
#             Chris Herborth (chrish@qnx.com)
#
# This is the new New and Improved Makefile for BeOS; it will:
#
# 1) automatically detect your platform (PowerPC or x86) if none is
#    specified; the default compiler is CodeWarrior for PowerPC, or
#    gcc for x86
#
# 2) let you cross-compile for the other platform (PowerPC or x86), in
#    theory
#
# 3) let you use Metrowerks CodeWarrior (default) or GNU C to build with
#    for either platfor, in theory
#
# To choose a specific architecture, define the ARCH environment
# variable on the make command-line:
#
# ARCH=what make -f beos/Makefile
#
# where "what" can be "powerpc" or "x86".
#
# To choose a specific compiler, define the CC environment variable on
# the make command-line:
#
# CC=compiler make -f beos/Makefile
#
# where "compiler" can be "mwcc" or "x86".
#
# Of course, you can combine these two:
#
# ARCH=powerpc CC=mwcc make -f beos/Makefile
#
# or:
#
# CC=gcc ARCH=x86 make -f beos/Makefile
#
# To automatically install the fresh new unzip, use the "install" target:
#
# make -f beos/Makefile install
