While playing gnuchess yesterday, I found the following bug:

Late in the game, the computer advanced a pawn to the 8th rank through a
particularly boneheaded oversight of mine, and promoted to queen. Seeing
this as most unacceptable, I "undo"'d twice to choose a different move.
It moved the two most-recently-moved pieces back, but did NOT turn the queen
back to a pawn! As my king and the pawn/queen were the only pieces on
my second rank, I was in check, and in a no-win situation. Before anyone
suggests I upgrade to 3.1, let me remind you that the v3.1 gnuchess.c breaks
our gcc-cc1 on this system.
