You mean you people don't have all warnings turned on, with -Werror as well? Here, how about I list the ones my project doesn't use, and why: -Waggregate-return - everything returns an aggregate in C++, and that's not necessarily a bad thing. -Wlong-long - We use long longs. -Wmissing-declarations - We don't need to declare every internal function before we use it. -Wmissing-include-dirs - Sadly necessary; gcc seems to include some on its own. -Wpadded - Everything's padded. -Wsystem-headers - I only wish I was in a position where this could be useful :) As K&R would say, let the machine do the dirty work. If a warning check exists, there's probably a good reason for it.
