-ffast-math is a little unfair.

Here are my CFLAGS: "-O3 -march=athlon-xp -mcpu=athlon-xp -mmmx -m3dnow -msse -fomit-frame-pointer -funroll-loops -fforce-addr -frerun-loop-opt -falign-functions=16 -falign-jumps=16 -falign-loops=16 -falign-labels=1 -finline-functions -pipe -mfpmath=sse,387 -fprefetch-loop-arrays -fmove-all-movables -ftracer -momit-leaf-frame-pointer"

If you wonder why I have march, mcpu, mmx, m3dnow and msse and all of the other redundant stuff, that is because some CFLAGS are stripped for some packages under Gentoo. march may be stripped but not mcpu, for example.

Edit to note that VS.net uses the same exact compiler. I have personally used it and can tell you that everything there is included. Also, from that page: "Microsoft C/C++ Optimizing Compiler and Linker. These are the same compiler and linker that ship with Visual Studio .NET 2003 Professional!"
