  No, I hadn't.  My main interest was in the GCC team's claim that the
generated code was faster.  Compiling with "make OPT='-mcpu=i686 -O3'"
did not make much difference at all.

  If they have any improved optimizations for recent x86 chips, I'd
like to see them folded into GCC.  I'd hate to see another egcs-style
  It doesn't look like I can just download a single source package
from them and wait 3 hours for it to build, so I won't plan on
pursuing this further.
