I assume you didn\'t notice anything, because (as the comment said), it is used only in DOS/DJGPP. DJGPP is a gcc (c/c++ compiler) port for DOS, as I know. But as we don\'t use dos for this game, it won\'t work.
That\'s just my guess though.
BTW, I would really like to see a mouse sensitivity setting IN-GAME (not from Windows).
