# GNU Makefile for hexen2 dhcc tool using GCC.
#
# To cross-compile for Win32 on Unix: either pass the W32BUILD=1
# argument to make, or export it.  Also see build_cross_win32.sh.
# Requires: a mingw or mingw-w64 compiler toolchain.
#
# To cross-compile for Win64 on Unix: either pass the W64BUILD=1
# argument to make, or export it. Also see build_cross_win64.sh.
# Requires: a mingw-w64 compiler toolchain.
#
# To cross-compile for MacOSX on Unix: either pass the OSXBUILD=1
# argument to make, or export it.  You would also need to pass a
# suitable MACH_TYPE=xxx (ppc, x86, x86_64, or ppc64) argument to
# make. Also see build_cross_osx.sh.
#
# To build a debug version:		make DEBUG=1 [other stuff]
