>Description:

	cc -Wformat warns about "flag `0' used with type `s'". But due
	to the manpage, this is correct and produces the expected
	code, too.

>How-To-Repeat:

	Try this code with "cc -Wformat foo.c":

	#include <stdio.h>
	main() {
	  printf("%08s\n", "12");
	}


>Fix:
	
	The following patch should fix the problem (not tested). Patch
	against file in /usr/src/contrib/gcc.
