Okay, hope you'll fix that! > To answer your specific question about GCC, only '-Wall' gets > used to compile. Good, that makes way more sense. I like to also use "-Wextra" when using gcc. If I understand patch correctly, I could then use: AC_APPEND_CFLAG_IFVALID([-Wextra]) It will then add "-Wextra"... but only if the compiler *accepts* that flag. BTW, I recently got a patch from someone on a project that force-added "-Wall" to configure.ac. Dale Visser's addition to autoconf is way better, because it doesn't presume that "all the world is gcc". --- David A. Wheeler
