#
#  Available options:
#
#    Environment variables:
#	CPU		optimize for the given processor.
#			default = pentium
#	GLU=[mesa|sgi]	specify GLU directory; can be `sgi' (requires GNU/C++)
#			or `mesa'.
#			default = mesa
#	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
#	HAVE_X86=1	optimize for i386.
#			default = no
#	HAVE_MMX=1	allow MMX specializations, provided your assembler
#			supports MMX instruction set. However, the true CPU
#			capabilities are checked at run-time to avoid crashes.
#			default = no
#	HAVE_SSE=1	(see HAVE_MMX)
#			default = no
#	HAVE_3DNOW=1	(see HAVE_MMX)
#			default = no
#
#    Targets:
#	all:		build everything
#	libgl:		build GL
#	libglu:		build GLU
#	libglut:	build GLUT
#	clean:		remove object files
#	realclean:	remove all generated files
#
