% cat t.cpp
#include <assert.h>

int f(int n) {
	switch (n) {
	case 1:
		return 1;
	default:
		assert(!"FAIL");
	}
}

% gcc -O2 -Wall -pedantic -Wreturn-type -Wno-return-type -c t.cpp

<no output>

What flags do I have to use to get an error or warning? I tried with
an without optimization, C and C++, and gcc versions 4.5.4, 4.6.3, and
4.7.2.
