--- Comment #23 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 32593 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32593&action=edit gcc49-pr59335.patch So, let's add the headers added in 4.9 and other stuff shouldn't be a regression from 4.9 then and can be added on a case by case basis. For 5.0 I hope something smarter will be added and we'll have some better plugin API than everything is the API.
