exactly pinpointed the problem only triggered on Windows Vista, provided
reference to docs and also a fix. There is much work behind Peter Lamberg's
excellent bug report. Thank You!

  edited it slightly. Now you should be able to use IPv6 addresses fine even
  with libcurl built to use c-ares.

  fix for it. It occured when you did a FTP transfer using
  CURLFTPMETHOD_SINGLECWD and then did another one on the same easy handle but
  switched to CURLFTPMETHOD_NOCWD. Due to the "dir depth" variable not being
  cleared properly.  Scott's test case is now known as test 539 and it
  verifies the fix.

response codes. Previously libcurl would hang on such occurances. I added
test case 1033 to verify.

CURLINFO_APPCONNECT_TIME. This is set with the "application layer"
handshake/connection is completed (typically SSL, TLS or SSH). By using this
you can figure out the application layer's own connect time. You can extract
the time stamp using curl's -w option and the new variable named
'time_appconnect'. This feature was sponsored by Lenny Rachitsky at NeuStar.

some systems" (http://curl.haxx.se/bug/view.cgi?id=1999181). The problem was
that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
macro when checking monotonic clock availability. This is now fixed and the
monotonic clock will not be used unless the feature test macro is defined
with a value greater than zero indicating always supported.

Fixed a file handle leak in the command line client if more than one
--stderr option was given.

  (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487567) pointing out that
  libcurl used Content-Range: instead of Range when doing a range request with

  verify.

enough at detecting compilation errors or at least it has been properly
configured to do so. Configuration heavily depends on this capability, so
if this compiler sanity check fails the configuration process will now fail.

  handshake with a SSLv2 server, and it turned out to be because it didn't
  recognize the cipher named "rc4-md5". In our list that cipher was named
  plainly "rc4". I've now added rc4-md5 to work as an alias as Phil reported
  that it made things work for him again.

  crashed libcurl. This is now addressed by making sure we use "plain send"
  internally when doing the socks handshake instead of the Curl_write()
  function which is designed to use the "target" protocol. That's then SCP or
  SFTP in this case. I also took the opportunity and cleaned up some ssh-
  related #ifdefs in the code for readability.

  libcurl to not tell the app properly when a socket was closed (when the name
  resolve done by c-ares is done) and then immediately re-created and put to
  use again (for the actual connection). Since the closure will make the
  "watch status" get lost in several event-based systems libcurl will need to
  tell the app about this close/re-create case.

  multi interface with pipelining enabled as it would wrongly check for,

  libraries are supported. Starting now, each underlying SSL library support
  code does a set of defines for the 16 functions the generic layer (sslgen.c)
  uses (all these new function defines use the prefix "curlssl_"). This
  greatly simplified the generic layer in readability by involving much less
  #ifdefs and other preprocessor stuff and should make it easier for people to
  make libcurl work with new SSL libraries.

  Hopefully I can later on document these 16 functions somewhat as well.

  I also made most of the internal SSL-dependent functions (using Curl_ssl_
  prefix) #defined to nothing when no SSL support is requested - previously
  they would unnecessarily call mostly empty functions.
