- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and

  the target host has only A records, it automatically falls back to an

  AF_INET lookup and gives you the A results.  However, if the target host has

  a CNAME record, this behaviour is defeated since the original query does

  return some data even though ares_parse_aaa_reply() doesn't consider it

  relevant. Here's a small patch to make it behave the same with and without

  the CNAME.

- Fallback to gettimeofday when monotonic clock is unavailable at run-time.

          if (status == ARES_ENODATA)

            {

              /* The query returned something (e.g. CNAME) but there were no

                 AAAA records.  Try looking up A instead.  */
