-From ee8750451b49d27b180517a4e35b636be0fae575 Mon Sep 17 00:00:00 2001
-From: Simon Kelley <simon@thekelleys.org.uk>
-Date: Tue, 23 Oct 2018 22:10:17 +0100
-Subject: [PATCH 03/32] Remove ability to compile without IPv6 support.
-
-This was the source of a large number of #ifdefs, originally
-included for use with old embedded libc versions. I'm
-sure no-one wants or needs IPv6-free code these days, so this
-is a move towards more maintainable code.
