Does this suggestion mean that the following strictly conforming program with
two translation units should link correctly, albeit perhaps with warnings?

	x.c:
		int F(){return 0;}
		int G(int i){return i;}
	y.c:
		int F(){return 1;}
		int G(int);
		int main() {return G(0);}

Won't most linkers flatly refuse to link this program
because F is defined twice?
