John Laskowski is the IBM SPEC representative.  I'm one of the people
who ran the SPEC suite for the announced numbers.  Here's what we've
got to say.

Several independent organizations have been able to verify the
IBM RISC System/6000 results.  Kavailya Dixit, from Sun Microsystems,
has verified the results and won the prize offered by the publication
that questioned RS/6000 results.

Since the RISC System/6000 was announced AFTER the SPEC Release 1.0
benchmarks were shipped, IBM specific makefiles for the RS/6000 were
not available on the SPEC tape (DEC, HP, and MIPS were all able to
include their vendor specific makefiles in the original tape).
This made it difficult for anyone to reproduce the RS/6000
results.  IBM specific makefiles will be available on
the next release level of the SPEC Suite.  This will make it much
easier for anyone to verify results.  In the meantime, a copy of
the IBM specific makefiles can be obtained by request from me.

P.S. The "exotic" compiler option used is "-O" for "optimize."
