Are you running similar gcc versions on both? I realize I forgot to
document what I was using:

HPPA: gcc version 2.95.3 20010315 (release)
PPC: gcc version 4.0.1 (Apple Computer, Inc. build 5363)
both Intels: gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)

Interesting that it's only the oldest-line tech that's showing a win
for me ...
