Patches 11 through 15 all seem incorrect; it's the responsibility of the
__ieee754_* functions to raise the correct exceptions, not of the
wrappers. Please make sure you don't have a compiler with a bug like
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95115 miscompiling those
__ieee754_* functions.
