Description:
------------
CURLOPT_FTP_SSL, CURLOPT_FTPSSLAUTH, and related options aren't registered in ext/curl.c. Without these, you can't do any ssl-related ftp bits...

patch:
http://www.gozer.org/test/php-4.4.4.ftpssl.diff

Reproduce code:
---------------
<?php
  $curl = curl_init();

  if($curl) {
    curl_setopt($curl, CURLOPT_URL, "ftp://ftp.mozilla.org/");
    curl_setopt($curl, CURLOPT_FTP_SSL, CURLFTPSSL_TRY);
    curl_setopt($curl, CURLOPT_VERBOSE, 1);

    curl_exec($curl);

    curl_close($curl);
  }
?>

Expected result:
----------------
* Connected to ftp.mozilla.org (63.245.208.138) port 21
< 220 (vsFTPd 2.0.1)
> AUTH SSL
< 530 Please login with USER and PASS.
> AUTH TLS
< 530 Please login with USER and PASS.
> USER anonymous
< 331 Please specify the password.

(unsupported here, but you get the idea)

Actual result:
--------------
* Connected to ftp.mozilla.org (63.245.208.138) port 21
< 220 (vsFTPd 2.0.1)
> USER anonymous
< 331 Please specify the password.
