Description:
------------
While move_uploaded_file() correctly worked with PHP 5.2.0, it stopped working with recent snapshots of 5.2.1-dev (maybe earlier). Appearently PHP (main/safe_mode.c?) checks whether the target file exists -- and this obviously is never true for a file which is going to be moved there (but isn't there yet).

./configure --disable-all --disable-cli --enable-fastcgi

Reproduce code:
---------------
(with safe_mode enabled and a correct file upload POST request)
<?php
  move_uploaded_file($_FILES['foo']['tmp_name'], "test.gif");
?>

Expected result:
----------------
The POSTed file should be moved to "test.gif" like in earlier PHP versions.

Actual result:
--------------
Warning: move_uploaded_file(): Unable to access /www/test.gif in /www/upload.php on line 2

No test.gif appears (although the permissions are correct; the uid of PHP is the same as the directory where test.gif should be put; nothing has been changed since the update from 5.2.0 to today's cvs snapshot)
