Strangely, my Alpha (July 3 -CURRENT) complains about this too, but my
i386 (June 24 -CURRENT) doesn't.  Here's my test program:

#include <stdio.h>

int
main(void)
{
        printf(NULL);
        return 0;
}

on Alpha, I get

des@dsa ~% gcc -Wformat -c /tmp/format.c
/tmp/format.c: In function `main':
/tmp/format.c:6: warning: null format string

on i386, I don't get a warning.
