Do we have functions that go by those names?  If not, removing the
definitions will leave us without this functionality, and that could
potentially break some applications out there, or even the libm
functions themselves, if some of them use those macros.

So I'd suggest instead to replace these macros with different
definitions which do not contradict C99.
