--- Comment #22 from Chen Gang <gang.chen.5i5j at gmail dot com> --- (In reply to Jakub Jelinek from comment #21) > Author: jakub > Date: Fri Nov 27 08:59:55 2015 > New Revision: 230999 > > URL: https://gcc.gnu.org/viewcvs?rev=230999&root=gcc&view=rev This way looks OK to me. But for C++, it has no pr63326 issue, do we still need to modify gcc/cp/parser.c? pr42979 is related with this issue, more or less. May this patch also fix pr42979 by the way? If this patch really fix pr42979, we will still need gcc/cp/parser.c (both C and C++ have pr42979 issue). Thanks.
