Just in-case anyone was ever curious about how well Wine performs with different C/XXFLAGs I did a test today with RC5 to see how much of a difference it makes with 3DMark 2001 SE, nothing major but if someone can think of a better benchmark to try, please let me know (I had hoped to try Oblivion or some such but it has no benchmark feature).

For reference I tried the same with Lame just to show how it would affect other programs:
