I'm afraid I ran this test on a ss20 UP machine, and not the ss20 SMP
machine I built on... Here's a new run for gcc-3.1 2002-04-08.

This was on a Debian Woody (test release) sun4m system with these
packages:

binutils                           2.12.90.0.1-1
dejagnu                            1.4.2-1.1
gcc                                2:2.95.4-14 (Debian prerelease)
gcc-2.95			   1:2.95.4-5 (Debian prerelease)
kernel-image-2.2.20-sun4dm-smp     9
libc6                              2.2.5-4

i.e., no threads as some suspect threads problems.
