Description:
------------
I tried to execute the example for interfaces in PHP 5.0.0b (beta 2) and got this result:

Fatal error: Cannot redeclare class exception in /home/billy/public_html/php5/interface.php on line 6

When I changed the word "Exception" to "Exception1" the code ran without a problem.

Probably the example needs to be changed, but I am not sure.

Reproduce code:
---------------
<?php
interface Throwable {
   public function getMessage();
}

class Exception implements Throwable {
   public function getMessage() {
       // ...
   }
}
?>


Expected result:
----------------
expect a blank page

Actual result:
--------------
Fatal error: Cannot redeclare class exception in /home/billy/public_html/php5/interface.php on line 6
