Be assured that I fully appreciate that projects do use -Werror. In fact, I do personally encourage people to use -Werror. However, the issue is very specific: we talking about -Wall. If something there is wrong as a default we should have a look at it whether it should be there at all, should it be improved, etc. -- Gaby
