e3b5673e98 - 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.

97333deb3f fallback to gettimeofday when monotonic clock is unavailable at run-time 2008-07-02 03:04:56 +00:00

67f139e016 - As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
not posix or anything and thus c-ares failed to build on hurd (and possibly
  elsewhere). The define was also somewhat artificially used in the windows
  port. Now, I instead rewrote the use of gethostbyname to enlarge the host
  name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
  define. I thus also removed the defien from the namser.h file where it was
  once added for the windows build.

  I also fixed init_by_defaults() function to not leak memory in case if
  error.

836fa69e2e - Sebastian made c-ares able to return all PTR-records when doing reverse
lookups. It is not common practice to have multiple PTR-Records for a single
  IP, but its perfectly legal and some sites have those.

9026dc2da4 - Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to
autoconf 2.57 usage (which is the version you have specified as the minimum
  version). It's a minor change but it does clean up some warnings with newer
  autoconf (specifically 2.62).

0f4664d27f Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in
several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
if it fails and the socket is closed the following code doesn't try to use
the file descriptor.

0f89a2e639 Steinar H. Gunderson modified c-ares to now also do to DNS retries even when
TCP is used since there are several edge cases where it still makes sense.

05b26e7566 Brad House provided a fix for ares_save_options(): Apparently I overlooked
something with the ares_save_options() where it would try to do a malloc(0)
when no options of that type needed to be saved.  On most platforms, this was
fine because malloc(0) doesn't actually return NULL, but on AIX it does, so
ares_save_options would return ARES_ENOMEM.

670273968c added ares_process_fd() to allow applications to ask for processing on
specific sockets and thus avoiding select() and associated functions/macros.
This function will be used by upcoming libcurl releases for this very
reason. It also made me export the ares_socket_t type in the public ares.h
header file, since ares_process_fd() uses that type for two of the arguments.

00ae13f966 - Guilherme Balena Versiani: I noted a strange BUG in Win32 port
(ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
  by hand or disconnect the network cable in Windows 2000 or Windows XP, my
  application gets 127.0.0.1 as the only name server. The problem comes from
  'GetNetworkParams' function, that returns the empty string "" as the only
  name server in that case. Moreover, the Windows implementation of
  inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
