libcurl wasn't built to use OpenSSL as that is a prerequisite for this
  option to function!

functional if libcurl is built against OpenSSL

  case 617 (which was added by Daniel Fandrich 5 Mar 2008).

support when curl didn't even have regular LDAP support.  It looks like
this could happen when the --enable-ldaps configure switch is given but
configure couldn't find the LDAP headers or libraries.

added --extvercmd parameter which can be used to specify an external command to display 'curl --version', f.e. with MinW32 crosscompile --extvercmd=/usr/bin/wine can be used.

  default instead of a ca bundle. The configure script will also look for a
  ca path if no ca bundle is found and no option given.

- Fixed detection of previously installed curl-ca-bundle.crt

SFTP quote command reported by Vincent Le Normand, but left it disabled.

- Added macros for curl_share_setopt and curl_multi_setopt to check at least
  the correct number of arguments.

any hard-to-grasp warnings in curl_easy_setopt() calls in applications.
Also delete superfluous semicolons.

reproduce the --ftp-create-dirs problem reported by Brian Ulm, but that
seems to need a call curl_easy_reset() which this test case doesn't do.

  CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the
  handle and uploaded another file to another directory that needed to be
  created, the second upload would fail. Another case of a state variable that
  wasn't properly reset between requests.

- I rewrote the 100-continue code to use a single state variable instead of
  the previous two ones. I think it made the logic somewhat clearer.

  CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the

a single state variable to make the code easier to follow and understand.

  (http://curl.haxx.se/bug/view.cgi?id=1911069) that identified a race
  condition in the name resolver code when the DNS cache is shared between
  multiple easy handles, each running in simultaneous threads that could cause
  crashes.

  does nothing with them, just to make sure libcurl users always use three
  arguments to this function. Due to its use of ... for the third argument, it
  is otherwise hard to detect abuse.

a "dummy" just to get things as fixed as possible in case we ever get the urge
to change this to actually mean something.

  works in C mode atm (http://curl.haxx.se/mail/lib-2008-02/0267.html ,
  http://curl.haxx.se/mail/lib-2008-02/0292.html )

(test 620 tests the just-fixed problem reported by Brian Ulm).

gssapi check. Cleans up curl-config --libs output when REQUIRE_LIB_DEPS=no

  easy handle if curl_easy_reset() was used between them. I fixed it and Brian
  verified that it cured his problem.

- Brian Ulm reported that if you first tried to download a non-existing SFTP
  file and then fetched an existing one and re-used the handle, libcurl would
  still report the second one as non-existing as well! I fixed it abd Brian
  verified that it cured his problem.

_USE_32BIT_TIME_T has been defined to get a 32-bit time_t

usage

select/poll calls will only be retried upon EINTR failures as
it previously was in lib/select.c revision 1.29

In this way Curl_socket_ready() and Curl_poll() will again fail
on any select/poll errors different than EINTR.

files, as questioned by Mike Protts. SFTP does for me but SCP doesn't
so test 617 is disabled for now.
