Ah yes, because compiler warnings are always viewed and acted upon.

Have you ever watched the compilation of a large open-source project,
done using the project's own build system and therefore the team's
preferred warning settings? It's normal to have such a spew of
warnings that you can't find anything interesting, or to have new
warnings in new versions of GCC be utterly useless for the same
reason.
