--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 45000 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45000&action=edit gcc9-pr86739.patch This works for me (well, make in gcc/ with recent gcc still builds and the preprocessed source from this PR with those tweaks compiles with GCC 4.1).
