Description:
------------
When including php-files using the require_once statement, PHP will see a generated path as being different from an absolute path if the casing of the directories are different. This should not be the case under WIN32 where users are used to case-insensitivity.


Reproduce code:
---------------
# A relative inclusion of myfile.php in the same directory
# C:/Inetpub/wwwroot/
require_once("myfile.php");

# An inclusion of myfile.php using an absolute path
# typed in lowercase (as WIN32-users often do)
require_once("c:/inetpub/wwwroot/myfile.php");

Expected result:
----------------
I would expect only one inclusion of myfile.php

Actual result:
--------------
I get two inclusions of myfile.php
