--- Comment #6 from Alejandro Colomar <alx at kernel dot org> --- Hmm, okay, Wextra as a first step makes sense. How about one release in Wextra, and then move it to Wall? As for ISO C, I'm not sure if ISO is a good place to start the deprecation. I don't like ISO inventing (or deprecating) stuff by decree. I prefer having at least one implementation doing the first step.
