--- Comment #1 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
These functions are only supposed to have results exact to the extent specified
in IEEE 754.  When both IEEE 754 and ISO C explicitly do not specify the sign
of a zero result, I don't think it's appropriate to slow down our
implementations to produce a more fully specified result.
