Just as a FYI you can greatly reduce your batch file and achive a faster crafty by using the following;
gcc -c -DNT_i386 -O3 crafty.c
gcc -c -DNT_i386 -O3 egtb.cpp
gcc -o crafty.exe *.o
By doing this you compile the crafty.c as one large object which allows for better optimization.

Do you have any figure about what kind of speed-up one could expect from doing this (not just with Crafty)?
Thanks,
Fabien.

I do not have any figures on other engines; I had some time a while back and was playing with the MingW compiler to see what kind of results I could get with Crafty (See my respone to Tord). I like you am a UNIX type and my crafty system is a Proliant 6000 Linux box and I use the Intel Compiler.
