Yes. Try mingw with msys. it works under windows. download the latest gcc compiler. then compile a version with profile info. produce profile info. then recompile with that and branches get optimized. should get your chess wizard, assuming it's a non-bitboard (gcc is horrible optimizing 64 bits code for 32 bits processors), a lot faster. It sure works for diep very fast.
