Perhaps someone could download the latest version of fdlibm and see
if it is already up-to-date with C99.

I'd rather we had the C99 math functions in libc.a.  What libm.a has
is mostly for historical reasons, and we developed our versions of
most of that stuff for libc.a (Eric's work) to free users from the
need to say -lm.  It doesn't make much sense to put that limitation
now when users want the new C99 math stuff: there's no history
involved, so we can do whatever we see fit.

That's true, those functions were not in C89.
