[Bug c/15657] New: -wall incorrectly diagnoses scanf("%a")

["paulmoore100 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

3.3.1 (suse 9) 3.2.2 (red hat9) 
#include<stdio.h>
void f()
{
 char *s=0;
 scanf("%a", &s);
}

cc -Wall on this incorrectly produces "float format, pointer arg(arg2)"
it should say "invalid or incomplete format" or something like that
