i don't think that's it.

i think the gcc folks have different goals.  they seem very interested in
lots of very sophisticated optimizations and support for every odd corner case.
(of course odd corner cases are exponential in sophisticated optimizations.)

i think their lack of success is indicitive that the problem they're solving is hard,
and they don't quite understand why it is so hard.

p.s. linux is doing the same thing. they've added 22 (by my count) system
calls this year alone.  all are performace hacks or corner-case jobs.
