--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Gcc does not provide math.h. nor defines the macro issubnormal.


In libstdc++, there are #undef for some macros to get around libc that define
some functions as macros.

If you are implementing something similar then you should be able to do that
too.
