Is this a real bug?
If both of -c COUNT and -w TIMEOUT are specified, ping exits by
timer _OR_ by the counter regardless of -f option.
If you want to ping really COUNT times, try -W TIMEOUT option.
... And please send your changes in the patch (or unified diff;
diff -u) format with your appropriate "sign-off" line, next time.
Thanks.
