I think the gcc guys are perfectly aware they are cheating with their
arithmetic to get speed.  For many problems this is okay.  Still, it's
quite questionable that the *default* is the speedy, incorrect version;
it would seem much better for a compiler to generate correct stuff by
default, and to have an override for the approximations.
