Some of the other warning are a little more pedantic, the most annoying is -Wsign-compare. OTOH a lot of code out there is clean enough to build without any warnings and with a moderate amount of pedantry from the compiler. OTOH just including extra headers isn't ideal - it can considerably slow down the compilation time. There are many subsystems that don't really separate their internal headers from their external ones.
