Subject: Crafty: Linux v Windows compilers

A question for Dr Hyatt (or anyone else!):

I run a Linux system, and am disappointed with the performance of my
Linux-compiled versions of Crafty 18.xx versus the supplied precompiled Windows
versions. The Windows version is about 20% faster in kN/sec on the same position
running under Windows/NT 4.0 *in a VmWare 3.1 virtual machine running inside
Linux*, than the native Linux version itself (compiled with egcs 2.91.66 with
-O3 on a K6/2 460MHz 192Mb). Same hash table sizes.

Am I doing something wrong with the compiles, or is egcs code really that
inferior to the Windows compilers?
