Description:
------------
Defining a private method in an extending class that matches the name of a private 
method in a parent class with a different signature currently triggers an 
E_STRICT. As the extending class shouldn't see the parent private methods, there 
is no reason to trigger an E_STRICT in this case.

Test script:
---------------
<?php

class A
{
  private function foo($bar)
  {
  }
}

class B extends A
{
  private function foo()
  {
  }
}

Expected result:
----------------
no E_STRICT error

Actual result:
--------------
PHP Strict standards:  Declaration of B::foo() should be compatible with 
A::foo($bar) in /Users/lsmith/htdocs/foo.php on line 15
