--- Comment #3 from Christophe Lyon <clyon at gcc dot gnu.org> --- Sorry Martin I didn't noticed you were looking at this PR. I've attached a small patch that checks whether %< has a "word" character immediately before, rather than a space; otherwise it warns in cases where %< is preceded by -, ", etc... When running the script, it warned in 3 more occurrences in gcc/cp/call.c, which I updated too.
