[Bug-gnubg] 50% decrease in evaluation speed

Hello all,

my name ist Joachim, I'm new in this group.
My first step to get involved ist to recompile the source.
Compiling for windows (xp) results in 50% less evaluation speed
compared to the binary download (27448 to 4029295).
I followed the instructions from Superfly Jon (08/02/06).
In both versions SSE is available and used, so the only change I applied was
to turn on SSE ( COMPOPT=-g -O2 -mms-bitfields -msse).
Is it possible that the gnu-compiler creates different machine code under windows
or is something wrong with my compiler settings?
Or maybe the checked out code from cvs is very different in terms of speed compared
to the code used in the binary download?

Thanks for any hint,
