This is *not* a good idea. The problem is that not all warnings are your own fault :) I have seen a lot of examples where a missing prototype or redefinition in OS headers results in a compile-time warning, and -Werror would definately be the wrong thing then. You should use -Werror only if you're afraid of not seeing stderr messages from gcc, or want gcc to stop compiling at the first error to avoid the usual cascade of weird, seemingly incorrect errors. :) -Wall good, -Werror bad. -pedantic could clash with any gcc-specific code such as the calculated-goto. -- Thomas Wouters <thomas@xs4all.net> Hi!
