Description:
------------
The bundled libssh2 in CVS fails to work under Windows.
You can connect, but the function "ssh2_auth_pubkey_file" fails always.

If you use the latest libssh2, you can use this function without a problem.

BTW: your PHP versions are out of date (I'm using 5.2.8).

Reproduce code:
---------------
<?php
$connection = ssh2_connect('shell.example.com', 22, array('hostkey'=>'ssh-rsa'));

if (ssh2_auth_pubkey_file($connection, 'username',
                          '/home/username/.ssh/id_rsa.pub',
                          '/home/username/.ssh/id_rsa', 'secret')) {
  echo "Public Key Authentication Successful\n";
} else {
  die('Public Key Authentication Failed');
}
?>


Expected result:
----------------
on my server: I expect "Public Key Authentication Successful"

Actual result:
--------------
A warning that the authentication failed and "Public Key Authentication Failed"
