[Bug other/36901] pedwarn() + -pedantic-errors + -w (inhibit_warnings) should not emit errors

["manu at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #10 from manu at gcc dot gnu dot org  2008-08-09 20:38 -------
Yeah, silly me, it obviously fails because there is no "next" pr36901.h to
include.

Since we include limits.h, we are at the mercy of the contents of the limits.h
that is found. This isn't very reliable. We just need to a pedantic warning in
the header. This works in x86_64, could you test on your side?
