Description:
------------
I think the require language construct may be broken in PHP 5.0.4 under Windows/Apache2 as it seems to ignore return statements in conditionnal blocks.

Note: if you set $myvar to 0 in the code, there's no such problem.

Reproduce code:
---------------
<? // testfile.php
$myvar = 1;
include('maininc.php');
myfunc();
?>

<? // maininc.php
if ($myvar == 1) { require('sndinc.php'); return; }
function myfunc() { echo "Exec'ed from maininc.php!!"; }
?>

<? // sndinc.php
function myfunc() { echo "Second included file..."; }
?>

Expected result:
----------------
I would expect the script to simply echo "Second included file..." and terminate.

Actual result:
--------------
Fatal error: Cannot redeclare myfunc() (previously declared in D:\HTTPd\www\tests\maininc.php:8) in D:\HTTPd\www\tests\sndinc.php on line 5
