--- Comment #13 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Created attachment 59960 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59960&action=edit Cleaned up patch with Harald's addition. This patch fixes some white space and merges in Haralds patch for optional argument passed to an f_c_string. I have not put together a test case there yet.
