>Description:
	When emacs is configured to use IPV6 (--with-ipv6 flag) the
	builtin LISP function open-network-stream does not work. The
	example below demonstrates this. For me it fails with:

		error creating socket: protocol not supported, mail

	If I change editors/emacs/Makefile to instead configure with
	--without-ipv6 the example below works as expected.
	For reference:
	# $NetBSD: Makefile,v 1.39 2000/06/24 17:03:37 minoura Exp $

>How-To-Repeat:
	Try reading news with GNUS in emacs, or try the following
	example:

	(let ((foo (get-buffer-create "foo")))
	  (open-network-stream "mail" foo "localhost" "smtp"))

	Put this code in the *scratch* buffer , put the cursor
	afterwards and press Ctrl-X Ctrl-E. You may need to change
	localhost to something that responds on port 25.
>Fix:
	Unknown. Probably easy for someone who knows IPV6?
