Bug description:  function symlink() crash under windows

Description:
------------
Create and Manipulate NTFS Junction Points doesn't work in PHP but it was
solved by www.sysinternals.com. They also offer the c-code free for
download.

I have tested it and it works very well.

You can download the free source code there:

Reproduce code:
---------------
$letters = 'abcdefghijklmnopqrstuvwxyz'; 
srand((double) microtime() * 1000000); 
$string = ''; 
for ($i = 1; $i <= rand(4,12); $i++) { 
   $q = rand(1,24); 
   $string = $string . $letters[$q]; 
} 
//----- this part can't work under windows
$handle = opendir($downloaddir); 
while ($dir = readdir($handle)) { 
   if (is_dir($downloaddir . $dir)){ 
     if ($dir != "." && $dir != ".."){ 
         @unlink($downloaddir . $dir . "/" . $filename); 
         @rmdir($downloaddir . $dir); 
     } } } 
closedir($handle); //------
mkdir($downloaddir . $string, 0777); 
// here symlink produce browser crash under windows
symlink($safedir . $filename, $downloaddir . $string . "/" . $filename); 
Header("Location: ".$downloadURL.$string. "/" . $filename);

Expected result:
----------------
start downloading but produce browser crash
