>Synopsis: cc -Wformat too sensitive
>Confidential: no
>Severity: non-critical
>Priority: low
>Responsible: freebsd-bugs
>State: open
>Class: sw-bug

Private FreeBSD site, Berlin, Germany
>Release: FreeBSD 2.2.1-RELEASE i386
>Environment:
>Description:
cc -Wformat warns about "flag `0' used with type `s'". But due
to the manpage, this is correct and produces the expected
code, too.
>How-To-Repeat:
Try this code with "cc -Wformat foo.c":
#include <stdio.h>
main() {
printf("%08s\n", "12");
}
>Fix:
The following patch should fix the problem (not tested). Patch
against file in /usr/src/contrib/gcc.
