Description:
------------
Symbolic links under Windows Vista doesnt work as expected anymore when using PHP 5.3 in combination with Apache 2.2.12.

See Code below.
Resolving to Base.php works. But using BASE_DIR in Base.php itself causes

Warning: require_once(C:\localhost\htdocs\page/lib/base/Database.class.php) [function.require-once]: failed to open stream: No such file or directory in C:\localhost\htdocs\page/lib/base/Base.php on line 7

Fatal error: require_once() [function.require]: Failed opening required 'C:\localhost\htdocs\page/lib/base/Database.class.php' (include_path='.;C:\localhost\php\pear\') in C:\localhost\htdocs\page\lib\base\Base.php on line 7

but sometimes it works, than i reload and it doesn't work again.
I don't know why. With PHP 5.2.9 it works as expected.


Reproduce code:
---------------
/* in C:\localhost\page/index.php */
// something like C:\localhost\page/
define('BASE_DIR', dirname(__FILE__).'/');

// the base dir is a symbolic link to C:\localhost\_base/
require_once(BASE_DIR.'lib/base/Base.php');



/* in C:\localhost\_base/Base.php */
require_once(BASE_DIR.'lib/base/Database.php');
