As the subject suggests I've checked in some code which checks if the
processor has get SSE enabled (when the exe is compiled with

I did notice a call to NeuralNetEvaluate in FindBestMoveInEval().  Which
doesn't use the 128 equivalent - does anyone know if this is correct?

Anyway in theory (I've only tested it on a P4) a SSE enabled exe should
run fine on an older machine (obviously using the old non-SSE code).  If
anyone has an old pentium or 486 to try it on that would be good.  In
fact any testing would help.
