this is test.php file

<?

for ($cnt = 0; $cnt<5; ++$cnt){

	require("test.inc.php");

	a($cnt);
}

echo "ok";
?>

-----------

and here is 

<?

function a($cnt){
	echo $cnt;
	return;
}

?>

----

the result is

0
Fatal error: Cannot redeclare a() in Unknown on line 3
-------
it is not necessary a bug since if the require is replaced by the code itself it gives the same error. But why the behavior is changed, in previous versions it works
