--- Comment #2 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Martin Sebor from comment #1) > > The test case makes the tacit assumption that argc is necessarily > non-negative. That makes sense for the argc argument to main but not in > other situations. Would it be possible to propose an update to the C standard that allows the argc argument to main to be unsigned? Could GCC start accepting unsigned argc as an extension so that -Wmain allows it?
