Didn't have enough time to check on LCTII, but would like to report that
the update does enhance the performance on FM on the AMD -- on my K6/233
with 48MBs of hash the short FM is now 142 (217 Kns) (used to be 128),
and the long FM 183 (242 Kns)(used to be 151) which is more than the
P233MMX in terms of nodes, but less in terms of FMs (??) Now, how does
one interpret this? The engines (be it Fritz 5.03 or 5.01) seem to be
the same -- 106496 bytes, date March 14, 1998.
