Aaron is using 18.12. I'd like to get him to use a newer build. I'm looking into
doing some AMD optimization for Crafty. If that turns out well, I'll run the
latest on my 3 Athlon-based boxes. Until then I'm not comparing my numbers
because I think it is a tad unfair to pit a compiler against Eugene. :-)
