To apply the patch file, move it to the directory containing the gltron source (gltron-0.70) and run patch -p0 < patch.diff

Additional notes

When running ./configure add the flag --enable-warn=off or else the program won't compile because it will treat warnings as errors.

If you're adding --enable-localdata then delete all Makefiles in the music directory before running the game, there should be only one file remaining there named song_revenge_of_cats.it
