I know Apple doesn't want you to run their OS on non-Apple hardware,
but I don't think we should reinforce that standpoint.  Could we just
match *-*-dawrwin*?

Also, I'm a bit confused by the Darwin vs. MacOS X naming game.  I
realize it would be quite a bit of work, but to me it would make sense
to exclusively use Darwin in comments, function names and file names
(appropriately capitalized).

Why do you need both Darwin and Darwin64?  We don't do this for other
operating systems that have both a 32-bit and a 64-bit variant.
