Description:
------------
I am running php5.2.1 as apache2.2 module
It seems that there is a problem with multiple classes in a single file with runkit_import.
The reproduce-code throws the following error:
Fatal error: Call to undefined method a::foo()

When i define 'class c' before 'class a' in the same file, everythings ok.

Reproduce code:
---------------
#file main.php
<?class b { public function foobar() { echo "foobar()\n"; } }
class a extends b {} runkit_import( "class_a.php" );
$a = new a();
$a->foobar();
$a->foo();?>
#---------------------------------------#
#file class_a.php
<?class a { public function foo() { echo "foo()\n" } }
class c {} # Define class c before class a in this file works.
?>

Expected result:
----------------
foobar()
foo()

Actual result:
--------------
foobar()
Fatal error: Call to undefined method a::foo() in X:\main.php on line 5
