[Nagiosplug-devel] Would appreciate some configure.in help

[Jeremy T. Bouse]

	Attached is a small patch to configure.in that I've done to add
a --with-ping6-command option similar to the already existing
--with-ping-command... My problem is I'm not that great at actually
generating the configure.in so I know this prolly is not too portable at
this time... This is in my work to get IPv6 support and with check_ping
it needs to know how to call the ping command for IPv6... 

	The situation I ran into was that in Linux I have a
/usr/sbin/ping6 that handles IPv6 pings where /usr/sbin/ping only
supports IPv4... However on my Solaris 9 build machine it uses
/usr/sbin/ping for both IPv6 and IPv4, you just give it the "-A inet6"
option for IPv6 otherwise it uses IPv4 by default... What I have in this
patch does not work for the Solaris solution but works fine for Linux...

	I would think the ideal solution I feel would be to have
plugins avoid calling system commands at all as check_ping, check_dns
and check_dig all suffer from similar issues because the call ping,
nslookup and dig through system calls respectively... However until the
time can be taken to make a better solution I'm working with what we
have as a base...
