Description:
------------
This issue was brought up in Bug #42830 but the bug was closed as 'Bogus' but to me it seems to be a valid issue:

I am working on a small framework of my own and all objects share a common ancestor (base object) that defines __construct as public.  I cannot redefine the visibility of __construct in the base without breaking other classes, yet I still want this derived, singleton to share the relation.

Addendum: This seems to be the case with any method, actually, not specific to __construct().  I tried defining a 'GetMessage()' method in the same class structure.  

Reproduce code:
---------------
class BaseObject
{
   public function GetMessage()  {  return "foo1";  }
}

class RequestObject extends BaseObject
{
   public function GetMessage()  {  return "foo2";  }
}

class CurrentRequest extends RequestObject
{
   private function GetMessage()  {  return "top secret";  }
}

Expected result:
----------------
No errors for restricting visibility of methods in derived classes (I can understand not letting you *increase* visibility of derived methods, but not the other way around).

Actual result:
--------------
PHP Fatal error:  Access level to CurrentRequest::GetMessage() must be public (as in class RequestObject) in C:\kristian\workspace\guild\foo.php on line 15
