>Description:
	I've upgraded my primary recursive DNS server to bind-9.5.0-P1
	when it was released and faces famous problem with
	bind reaching FD_SETSIZE=1024 limit easy. The entry 2406
	of CHANGES file of bind-9.5.0-P2 describes environment variable
	it supports to raise this limit at compile time.

	Let's support it with port knob to get all advantages it gives.
	
>How-To-Repeat:

	Run busy recursive DNS server with bind-9.5 built
	using dns/bind95 port with default settings.

>Fix:

	With this patch, one can build dns/bind95 with the following
	command:

	make WITH_FDSETSIZE=4096
