Is this valid ANSI C (or dpANS or whatever you want to call it):

	void f(char);

	void f(c)
	   char c;
	{
	}

The version of GNU cc I have complains:

	t.c: In function f:
	t.c:5: argument `c' doesn't match function prototype
	t.c:5: a formal parameter type that promotes to `int'
	t.c:5: can match only `int' in the prototype

Is this rule for real, or is this just a gcc bug?
