As far as 'chess' goes, 17.7 and 17.8 are identical.  Someone pointed out a
few problems with compiler warnings on different platforms, dealing with passing
a long long to an fseek() call when it should have been a long, for one example.

17.8 cleaned this up, as well as a couple of other problems (one was the bench
command would crash and burn if you had no books.bin file).

Engine-wise, both are identical.  I played the first weekend with 17.7, the
second with 17.8...  both play identical moves, with identical scores and
node counts (if you don't use SMP).

I thought I would release 17.8 "as is" as a reference point for the ICC
tournament version, in case any questions ever come up about "Hey, my
crafty won't play that move ever, I think it had some human intervention."
This version can be used by anyone to debunk such a statement.
