With the Windows Intel C++ compiler, others have been able to get much faster
speeds than I can get with the Linux Intel C++ compiler. In one case, we used
the same make target on the same hardware, and got significantly different
speeds (I got 754 Knps, he got 960 Knps).

I am also unable to get both PGO and IPO to work together with Crafty so far,
but I was able to get it to work for something simpler (TSCP) for a 30% speed
increase over using only one or the other. Maybe getting both of these to work
together for Crafty is the key.

So far I've only managed to either break the make file, or get compiler errors
if I try to compile it on the command line :)
