New Crafty 17.10 code tonight

Revision notes from main.c:
* 17.10 minor change to "threat" extension now only extends if the null- *
* move search returns "mated in 1" and not "mated in N". this *
* tends to shrink the trees a bit with no noticable effect in *
* tactical strength. EvaluatePawns() was not doing a reasonable *
* job of recognizing blocked pawns and candidate passers. it did *
* not do well in recognizing that the pawn supporting a candidate *
* could not advance far enough to help make a real passed pawn. *
* minor change to RepetitionCheck() to not count two-fold repeats *
* as draws in the first two plies, which prevents some odd-looking *
* repeats at the expense of a little inefficiency. Ugly repetition *
* bug fixed. rephead was off by one for whatever side crafty was *
* playing which would screw up repetition detection in some cases. *
* minor bug in main() that would report stalemate on some mates *
* when the ponder score was forgotten.

No exe yet.

Unless you don't mind a tweaked one. [Look at the message below this one]
I wonder how in tarnation the ones on Dr Hyatt's FTP site are so darn tiny? (more than 100K smaller than the one I compile).

My FTP site

I was also tempted to say "size isn't everything" LOL
Thanks

Anytime I've fiddled with things like for example the optimizer thing in the makefile, like -O3 to -O6 or 7, it'll end up running things faster if I pick the right one, but the size of the exe will also grow. I don't recall if lumping all the .c files into one big lump has the same effect, I think it does. I've never suceeded in compiling Crafty that way though, only the small potato programs.
