If I didn't see such errors and then saw new ones when I recompiled, I'd be annoyed. To me, the uninitialized variable warnings are quite important; if I specify -Wall, I have asked for all warnings, not just all warnings before the first error. > Even a programmer who sees a fatal error in > one routine might want to also see an uninit-var warning in a > subsequent, distinct routine. Yes, many programmers want to catch as many errors and warnings as possible in one compile. This is particularly important for large projects. Please let's consider the consequences carefully before making this change. Is it really that much of a performance win?
