That might be the theory, but in practice this is simply false.
Different toolchains produce different warnings, and not all patches
always get test-built on every target (especially on obscure
architectures).  And since it's false that no warnings exist, that means
sometimes even when a patch is test-built, some newly introduced
warnings get missed (I got an e-mail pointing out such an occurance just
today).
