# 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.

# X86=1 optimize for x86 (if possible, use MMX, SSE, 3DNow).
