That define isn't hurting anyone.

Actually these should all be deleted because they mean you have to have
a xgifb_info variable and they hurt readability by hiding stuff behind a
define.  It would be better to remove them all than to just remove one
from the middle.  That's a more complicated patch, but it's a useful
patch.
