#36 check_ping patch for RH7.3

[Anonymous]

The following diff patches the check_ping.c file from
netsaint-plugins-1.2.9-4.tar.gz so that it will properly
parse the output of the /bin/ping from RH7.3 (maybe
earlier versions too, I no longer run previous versions).
This patch works with Nagios. Note that you have to add
something like:

--with-ping-command="/bin/ping -n -U -c %d %s"

to the options for the configure script from the
aforementioned tarball. Make sure that
PING_PACKETS_FIRST is defined if you use the above
option for configure. I think the "-U" option is superfluous
as I noticed no difference in ping's output when it was
removed. This patch should be suitable for incorporation
on all systems, not just RH7.3.

Diff output is attached, and also follows, at line
beginning with "402d".
