For those who might be interested, I've recently benchmarked gcc 4.6.3 (and

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 ;-)
