You have to be _very_ careful compiling for the AMD chips. They did _not_
implement the full PII core instruction set, including the conditional move
instructions.  AMD users complain about crafty all the time, as they compile
with my Makefile (which specifies arch=i686 and enables cmov among other
things) and then the thing crashes and burns when the CPU faults on those
instructions...

You have to compile for a 586 architecture (original pentium) or AMD won't
work..
