Description:
------------
Php 4.3.4 still has this the issue reported in bugs 
#11326 and #9673.  Even though #11326 lists it as fixed 
in (CVS/4.0.7).

Did the behavior change again?  Is there a switch 
somewhere I'm missing?

If not, would it be possible to add a switch (or another 
function) so that includes could be based on the file 
calling the include?

Reproduce code:
---------------
//index.php in ./
include_once("./include/A.class.php");
$a = new A();
echo $a->printer();

//A.class.php in ./include
include_once("./B.class.php");
class A {
  function printer() {
    $b = new B();
    return $b->printer();
  }
}

//B.class.php in ./include
class B {
  function printer() {
    return "did it work?";
  }
}

Expected result:
----------------
did it work?

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