I've applied, but I'm not super happy with the proposed solution
because it's not upstreamable. Can you instead work on a different
patch that adds a autoconf cache variable that allows to override the
result of the "inet_pton is broken" test without patching the
configure.ac ?

See
http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Caching-Results.html
for more details.

Thanks!

Thomas
