Subject: [PATCH] wget 1.9.1: Make it work when you have no IPv6 support in the
 kernel - if it fails to create an IPv6 socket because of lack of kernel
 support switch the internal default to IPv4 and retry the failed connection.
 The default change will apply to all future sockets (for this run of wget) as
 well. Should close #1919 and #2390.

+If the kernel has IPv6 support then wget tries to create sockets using
+AF_INET6 and then gets an EAFNOSUPPORT error, which it treats as a
+connection failure, resulting in wget not being able to work. This patch
+makes it switch it's default protocol to IPv4 when it sees that IPv6 isn't
+supported in the kernel.
