Description:
------------
When a typelib is imported which defines a constant which has
already been defined, the COM extension is supposed to report
this, if com.autoregister_verbose is enabled and the imported
constant has the same value as the already defined constant.  This
(usually) does not happen, though.


Test script:
---------------
<?php
ini_set('com.autoregister_verbose', 1);
define('ADSTYPE_INVALID', 0);
$root = dirname(array_change_key_case($_SERVER, CASE_UPPER)['COMSPEC']);
com_load_typelib("$root\activeds.tlb");
echo "---DONE---\n";

Expected result:
----------------
Warning: com_load_typelib(): Type library constant ADSTYPE_INVALID is already defined in %s on line %d
---DONE---

Actual result:
--------------
---DONE---
