--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
We are using that #c13 patch successfully for almost 18 months now in Fedora.
As type promotion/demotion patch is not (sadly) going to happen for GCC 5, I
still think it would be worthwhile to apply it temporarily, until type
promotion/demotion is written.
