Subject: Bitboards, Borland and pipelines.

I suspect my favorite Borland compiler (C++ Builder 4.0) doesn't handle 64 bit
operations too well. As does Watcom. Presumably VC and newest GCC handle 64 bits
more than 50% faster, because they utilize the pipelines better. Or so I'm told.

Anyway: if I want to keep that compiler, is there any way I can make it's 64 bit
operations faster? Quite simple things like BB ^= (1ui64 << Sq) seem to take way
too much time.

(The comiler allows inline asm. Even MMX opcodes, if I'm not misinformed)

Any thoughts on this are appreciated!
