+# ENDIAN_FORCE: forces the endian-check to give a certain result. Can be either BE or LE.
+# WINDRES: the location of your windres
+# CC_HOST: the gcc of your localhost if you are making a target that produces incompatible executables

 # Experimental (does not work properly):
 # WITH_DIRECTMUSIC: enable DirectMusic MIDI support
