Description:
------------
When in cgi mode attached php script is classed as a parse error, I get:

[roadkill@synsrv1 roadkill]$ php -l blah.php
PHP Parse error:  parse error, unexpected '=', expecting ')' in /home/roadkill/blah.php on line 2
Errors parsing blah.php

When you run the script in isapi mode it works fine.

I tested this bug on php 4.3.4 and 4.3.9-dev on windows xp
and php 4.3.6 and 4.3.8 on Linux (Fedora Core 2)

This is NOT an issue in php 5 (on Windows at least)

This is an issue for me because I have a php syntax check in the commitinfo file for cvs and it won't commit because it claims a parse error.

Reproduce code:
---------------
<?php
function test(&$bar = null){
        echo "No parse error!";
}
$var = "hello";
test($var);
?>


Expected result:
----------------
No parse error!

Actual result:
--------------
PHP Parse error:  parse error, unexpected '=', expecting ')' in /home/roadkill/blah.php on line 2
