From ee8750451b49d27b180517a4e35b636be0fae575 Mon Sep 17 00:00:00 2001
From: Simon Kelley <simon@thekelleys.org.uk>

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.
