["janis187 at us dot ibm dot com" <gcc-bugzilla@gcc.gnu.org>]

The regression in PR 13070 was introduced or exposed with this patch
to both mainline and the 3.3-branch:

2003-03-17  Roger Sayle  <roger@eyesopen.com>

        * decl.c (duplicate_decls): Use the new type when prototyping
        anticipated decls, even when the types match.  This defines the
        exception list for the built-in function.

The regression hunt took place on i686-pc-linux-gnu using the following
testcase, modified to not require header files, with -Wformat:

extern "C" int printf (const char *, ...);
int main ()
{
  printf ("%d\n", 1, 1);
}
