James Brown 63ee97b1ee Fix using MAD -without- Vorbis, and remove COMPRESSED_SOUND_FILE define.
Please keep in mind that if you put an 'else' statement in an if clause, keep in mind that if the code it's supposed to
'else' is in another define.... and that isn't set... the NEXT statement of code will be used as the 'if..else'
condition.
