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.
DES
