Which is indeed my point. If you cannot distinguish it from incorrect
uses, you shouldn't be warnign the user, because the compiler obviously
doesn't know enough to make a sufficiently educated guess.

That said, a good compiler _can_ make a good warning. But to do so, you
have to actually do value analysis, instead of just blindly warning about
code that is obviously correct to a human.

Until gcc does sufficient value analysis, that signed warning is annoying,
worthless and a damn pain in the ass.
