--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Ricardo Abreu from comment #5) > The sentence I quoted says -Wall enables a certain group of warnings, not > flags. It goes on to characterize that group. It conveys information on its > own, without directing to sub-flags. Except the VERY NEXT paragraph talks about the specific sub-flags it turns on. It seems like you're trying pretty hard to find alternative meanings which don't actually make sense in the context.
