#
#  Available options:
#
#    Environment variables:
#	CFLAGS
#
#	GLIDE		path to Glide3 SDK; used with FX.
#			default = $(TOP)/glide3
#	FX=1		build for 3dfx Glide3. Note that this disables
#			compilation of most DMesa code and requires fxMesa.
#			As a consequence, you'll need the DJGPP Glide3
#			library to build any application.
#			default = no
#	X86=1		optimize for x86 (if possible, use MMX, SSE, 3DNow).
#			default = no
#
#    Targets:
#	all:		build GL
#	clean:		remove object files
#
