#
#  Available options:
#
#    Environment variables:
#	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
#	DXE=1		use DXE modules (see README.DJ for details).
#			default = no
#
#    Targets:
#	<file.exe>	build a specific file
