That ceased to be true around summer (Northern Hemisphere) last year.  Today,
the C compiler and optimizer has very few bugs left.  We found a few ourselves
that have been fixed by now (3003 update).  Personally, I believe that gcc will
never beat xlc, but having some results will of course be very wellcome.
