/* Technically, none of the format functions should be implicitly declared;
   either the implicit type is wrong, the function has variable arguments
   or it requires a type declared in a header.  However, some bad programming
   practice uses implicit declarations of some of these functions.
 
   Note that printf is not used in this test because of the declaration
   of it as a built-in function.  */
