Here is the number for the right position (Crafty).  Somehow my script before
didn't execute the command to set a FEN position.  On my PII/400 notebook, I get
159.43 seconds.

Note that I don't consider this test very worth-while...  there are several
ways to write this code...  I use the Check() function after each move, when
it can be written without doing so...  I also do a lot of stuff to save a path
for each distinct set of moves (root to tip) something I wrote for Stefen J. to
help him debug something new he is doing.

In crafty, my move generator time is < 10% of the total time, which means
this isn't the number that is important for overall search speed...
