No, not the same at all.  I want a warning because, like most people, when
I have a constant in a conditional it is usually a mistake.  If it isn't
then I ignore the warning.  Note that
	i = 0;
	start_loop:
		if( i >= 10 ) goto end_loop;
		...
		i++;
	goto start_loop;
	end_loop:
is a "valid language construct" but most people use
	for(i=0; i<10;i++) {
		...
	}
