[gnutls-devel] ipv6 vs ipv4 vs udp

The fallback from v6 to v4 works well for tcp, but not for udp.

I get something like:

:; gnutls-cli -u -p 5555 liberty.jhcloos.com
Processed 159 CA certificate(s).
Resolving 'liberty.jhcloos.com'...
Connecting to '2001:4830:1662::53:5555'...
*** Fatal error: The operation timed out
*** Handshake has failed
GnuTLS error: The operation timed out

There is an openssl s_server -dtls1 listening on that port (v4 only).
gnutls-serv -u (debian's version 3.0.22-3+really2.12.20-6) failed
complaining that -u (or --udp) were unknown.
