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).

-pipe only speeds up compilation, not the resulting machine code. -Wall makes gcc show more warnings about the code and again, it does not speed up the code.
