Q_OS_DARWIN incorporates all Darwin versions: OS X, iOS but also all of the free \
versions. It's a good thing they're dead in the water because they typically use(d) \
X11.

AFAIK, `MAC_DISPLAY` was just a variable that wasn't supposed to be defined. Its only \
merit was that it allowed a single user to have multiple klauncher sockets ... but I \
doubt that'd ever be relevant.
