This is probably the best result I have ever seen from Crafty.  I am simply
running some "sanity checks" to make sure everything is functioning, after a few
recent changes.  Here is my first test, WAC at 1 second per move:

total positions searched..........         300
number right......................         299
number wrong......................           1
percentage right..................          99
percentage wrong..................           0
total nodes searched..............   109706792
average search depth..............         4.6
nodes per second..................     6522401

It misses #230.

I re-compiled with Dann's favorite -DDETECTDRAW and at one second per move,
blasted out the following result:

total positions searched..........         300
number right......................         300
number wrong......................           0
percentage right..................         100
percentage wrong..................           0
total nodes searched..............   103251953
average search depth..............         4.5
nodes per second..................     5713998

I will try to run some other tests as I continue looking at things.  I am also
once again experimenting with the -DFUTILITY stuff that Jeramiah wrote, to see
how it affects things on this really monster box.

BTW for those that have asked, "crafty" is playing on ICC most of this week
using this box.  Scrappy is running on my normal dual xeon 2.8 all the time...
