Stranger and stranger.. On sparc64 from:
peter@panther[4:21pm]~-104> uname -a
FreeBSD panther.freebsd.org FreeBSD 5.0-CURRENT #2: Sun Jul 7 20:52:14 PDT 2002er
peter@panther[4:21pm]~-105> cat foo.c
#include <stdio.h>
#include <err.h>
int
main(void)
{
printf(NULL);
err(1, NULL);
return 0;
}
peter@panther[4:22pm]~-106> cc -O -Wformat -c foo.c
peter@panther[4:22pm]~-107>
ie: it looks like it is completely disabled. Maybe the sparc64 tinderbox
host is simply out of sync with -current?
Cheers,
