There's a solution for that (two solutions in fact, either a php.ini setting 
or a different variable):

http://www.symfony-project.com/trac/ticket/842

So I suppose the canonical solution would be something like:

$thispage = (isset($_SERVER['ORIG_SCRIPT_NAME'])) ? 
$_SERVER['ORIG_SCRIPT_NAME'] : $_SERVER['SCRIPT_NAME'];

How's that?  That should work anywhere, right?

(Disclaimer: I never use PHP as a cgi script and can't test this.)
