Why? Not that I'm arguing, I'm just curious to know why such a primitive
operation is so slow. If the eight or so instructions that gcc generates
to do this (I just checked) can be replaced with the two FPU
instructions described earlier, or a cunning integer arithmetic hack,
then why doesn't gcc do this by default?
