#
# To cross-compile for Win32 on Unix, you must pass the WINBUILD=1
# argument to make. It would be best if you examine the script named
# build_cross_win32.sh for cross compilation.
#
# Build Options:
#
# OPT_EXTRA	yes  =  Some extra optimization flags will be added (default)
#		no   =	No extra optimizations will be made
#
# COMPILE_32BITS yes =  Compile as a 32 bit binary. If you are on a 64 bit
#			platform and having problems with 64 bit compiled
#			binaries, set this option to yes. Default: no .
#			If you set this to yes, you need to have the 32 bit
#			versions of the libraries that you link against.
#		 no  =	Compile for the native word size of your platform,
#			which is the default option.
#
# The default compiler is gcc
# To build with a different compiler:	make CC=compiler_name [other stuff]
#
# To build for the demo version:	make DEMO=1 [other stuff]
#
# if building a debug version :		make DEBUG=1 [other stuff]
