--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
In this case gcc has nothing to do with this. Since defining issubnormal inside
std is undefined behavior there is nothing to be done.
Also you don't need a builtin since fpclassify is there already.
When issubnormal is added to the c++ standard, libstdc++'s will add it too.
