Description:
------------
The PHP Manual said: filetype() will also produce an E_NOTICE message if the stat call fails or if the file type is unknown.

However, in fact, with PHP 5.2.0, Windows Xp Sp2, a E_WARNING message is returned:
Warning: filetype() [function.filetype]: Lstat failed for W:/ in D:\wvbsrc\mailing\demos\lib\core\WVB\View\Drivers\WVB_View_Standard.php on line 73


Reproduce code:
---------------
if (filetype('W:/') === false)
{
	echo "Hello";
}

Expected result:
----------------
Notice: filetype() [function.filetype]: Lstat failed for W:/ in D:\wvbsrc\mailing\demos\lib\core\WVB\View\Drivers\WVB_View_Standard.php on line 73

Actual result:
--------------
Warning: filetype() [function.filetype]: Lstat failed for W:/ in D:\wvbsrc\mailing\demos\lib\core\WVB\View\Drivers\WVB_View_Standard.php on line 73
