For those who might be interested, I've recently benchmarked gcc 4.6.3 (and 3.4.2) vs. Intel v11 and Microsoft (in Windows 7) here:

For the math functions, this is normally more a libc feature, so you might get very different results on different OS. Then again, by using -ffast-math, you allow the math functions to return any random value, so I can think of ways to make it even faster ;-)

Thanks, Marc--I added results from the 64-bit version of MS VC 10 via your link.
