No idea.  I didn't try to make this "fast" at all.  It was designed to
be a debugging tool for the move generator (for me), not as a performance
test.  Although it has been used for that.  It is reasonable to compare
perft for crafty version X on machine Y vs perft for crafty version X
on machine Z, to compare the two machines.  Compareing two different
programs' perft times doesn't mean a lot unless both programs have been
optimized to make it efficient.  I simply wrote it to be simple.  IE I
would turn off a _lot_ of Make/Unmake overhead to simply run perft as fast
as possible...
