BIND 8.2.1: Lame servers

[Mark_Andrews at isc.org]

	The following patch should correctly set RD on the outgoing
	messages to the forwarders.  This will have only affected
	people using forwarders in "forward first;" (default) mode.

	The impact of not applying this patch, is if your forwarder(s)
	has not already cached the answer to the query your server
	will have to fall back to the nameservers for the zone.

	For those sites using "forward only;", n is already zero so
	this bug will have had no impact.

	For those sites not using forwarders, there is potential to
	set RD if you have filled up the q_addr array, otherwise it
	is off as expected.

	Mark
