Amen. If we include a warning in -Wall then it is because we believe it to be generally useful and likely to uncover common bugs/mistakes. It is therefore reasonable for users to issue -Wall -Werror even in application delivery mode. (I know I systematically turn it on for some of my programs and when delivering code base to my students.) In fact, if a warning generates too many false positives or annoying diagnostics for idiomatic constructs, then it is a good indication that it not ready for -Wall. -- Gaby
