--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
GCC 4.9 behaves the same way with -std=c11, GCC 5 behaves the old way with
-std=c99. -std=c11 turns on unicode literals, i.e. u"str", U"str" and u8"str".
So for #u"str" you really need to put there whitespace, so that it isn't
parsed as # followed by u"str" string literal.
