--- Comment #27 from Matthew Woehlke <mw_triad at users dot sourceforge.net> --- (In reply to Marek Polacek from comment #26) > Perhaps we could invent __builtin_fallthrough or some such. Yes, I was expecting there would be some alternate spelling for cases where C++11 attributes are not available, e.g. using __attribute__ or __builtin_fallthrough or some such. Please support [[gnu:fallthrough]] also, though, for consistency with clang (and it gives more weight to eventually making [[fallthrough]] standardized).
