--- Comment #6 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
The issue is the use of -Os to build libstdc++. Gabriel, it looks like
fpclassify needs a conditional as well to avoid the __MATH_TG version for (C++
and float128 support), for the same reason as isinf but only applicable when
-Os is used to build libstdc++.
