-w prevents any warnings being printed at all, it couldn't be used to turn off -Wstandard then selectively re-enable individual options, e.g. with -Wno-standard -Wmain Introducing a new switch would mean there's a single -Wno-standard switch for those who want to restore the old default behaviour, so they don't have to explicitly add -Wno-aaa -Wno-bbb -Wno-ccc etc. Maybe -Wstandard isn't the best name though, as "standard" usually means something quite specific for compilers, and the warning switch wouldn't have anything to do with standards conformance.
