Description:
------------
The scandir() doc page mentions an optional 2nd parameter that may contain 
SCANDIR_SORT_NONE.  But that constant does not exist.

http://us3.php.net/manual/en/function.scandir.php

If I grep the PHP source I can not find any match for SCANDIR_ anywhere.


Test script:
---------------
<?php
        $files = scandir( '/tmp', SCANDIR_SORT_NONE);
        $cnt = count($files);
        echo "{$cnt}\n";
?>


Expected result:
----------------
I expect a count of files in /tmp.

Actual result:
--------------
 # php  tmp.php
