Yes, that's what I thought too at first. But as I just said on the bug
tracker, all that counts is obtaining the correct result in the fastest
possible way. And this seems to be the float version.
Therefore, a platform for which another implementation is faster should
simply use another implementation (like we do for 32-bit intel already
which uses its own faster fixdiv implementation).
