main source tree, so no more pkgsrc patches. Changes from version 17.13:
another endgame evaluation problem fixed. the outside passed
pawn code worked well, up until the point the pawn had to be
given up to decoy the other side's king away from the remainder
of the pawns. Crafty now understands the king being closer to
the pawns than the enemy king, and therefore transitions from
outside passer to won king-pawn ending much cleaner.
new command "selective" as requested by S. Lim, which allows the
user to set the min/max null move R values (default=2/3). they
can be set to 0 which disables null-move totally, or they can be
set larger than the default for testing.
minor changes to init.c sent by Eugene Nalimov to handle 64 bit
pointer declarations for win64 executable compilation.
NetBSD changes included along with a new Makefile that requires
no editing to use for any known configuration ("make help" will
explain how to use it). this was submitted by Johnny Lam.
serious changes to the outside passed pawn code. the evaluator
now understands that outside passers on _both_ sides of the
board is basically winning. same goes for candidate passers.
