--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
First of all, note that math.h header comes from the C library, not GCC, so
likely glibc in your case.
And, please learn about Feature Test Macros that affect the namespace.
DOMAIN is part of SVID support, is included in e.g. _DEFAULT_SOURCE or
_GNU_SOURCE. So e.g. if you compile with -D_XOPEN_SOURCE=700 or various
others, DOMAIN will not be visible.
