#
#  Available options:
#
#    Environment variables:
#	FX_GLIDE_HW	build for the given ASIC (h3).
#			default = h3
#	H4=1		High speed Avenger.
#			default = no
#	OPTFLAGS	pass given optimization flags to compiler
#			default = -ox -5s (Pentium, stack)
#	DEBUG=1		enable debugging checks and messages
#			default = no
#	USE_X86=1	use assembler triangle specializations!
#			default = no
#	USE_3DNOW=1	allow 3DNow! specializations. However, the true CPU
#			capabilities are still checked at run-time to avoid
#			crashes.
#			default = no
#	TEXUS2=1	embed Texus2 functions into Glide3.
#			default = no
#
#    Targets:
#	all:		build everything
#	glide3x:	build Glide3x lib
#	clean:		remove object files
#	realclean:	remove all generated files
