/* Test for format attributes: test default attributes are applied
to implicit declarations. */

/* { dg-do compile } */
/* { dg-options "-std=gnu89 -Wformat" } */
/* We can't #include "format.h" here. */
/* 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. */
