>Description:
	The putc and getc macros do not function correctly when the pointer
	argument is of type (void *).  They should, to properly behave like
	functions with prototypes in scope.
>How-To-Repeat:
	#include <stdio.h>

	main () {
		void *v;

		v = stdin;
		getc(v);
		return 0;
	}
>Fix:
	Add casts to (FILE *) in <stdio.h>.

	(Unfortunately, this will introduce a lack of warning for non-pointer
	arguments.)
