You need to review the compile options for gcc-3.1, they have changed.
Important things like
you can now flag for pentium3 or pentium4, and that alone made a lot of
difference for me.
(By the way, for most modern Pentiums, I though designating pentiumpro was
faster)
As I said in my email to you, the work code I have tested, which does a lot
of scene generation
work, is about 10 - 15% faster with gcc-3.1 / Cygwin. The executable is much
larger, but
judicious use of strip can help out there.
