Description:
------------
Require triggers __autoload

Reproduce code:
---------------
File teste.php 

<?php
class teste extends acs_activerecord {
    public function __construct() {
        parent::__construct();    
    }       
}
?>

File other.php

require("teste.php");

This will trigger my autoload function (which is declared and included, but not shown here), which will try to load the file where the acs_activerecord is

Expected result:
----------------
I would expect it not to trigger the autoload function.
The autoload function should be triggered when I instantiate the class teste

Actual result:
--------------
I have xdedub and the cachegrind shows the autoload function being called when the file teste.php is required
