Is it one of the vector models ( YMP, C90, J90 etc) or one of the T3D / T3E models? These two families have different binary formats. Also i suspect Crafty will not do very well on a T3E without a LOT of tweeking. (Sorry, i don't have access to either to help with compiling.) I have heard that GCC is not a lot worse, and is occasionally better, than the commercial compilers on these machines, but it's hard to imagine a Cray being sold without the commercial compilers installed. I think having an expert recode the rotated bit-board stuff in assembler might be a significant win on a Cray. Assumptions about word size often come unstuck on Cray vector machines (short, int, long are all 64 bits!) but Bob has been around long enough that he probably didn't get caught by this?
