Problem with __FILE__ magic constant

We picked up a helpdesk script from sourceforge, Mantis. This script
uses the __FILE__ magic constant to ostensibly derive the path to the
include directory from a script in the top level directory.

Reading the doc about __FILE__ did not gain me enough insight as to what
is going on.

My testbed is running PHP 4.1.0 but the server where it is to run is
4.0.6. The script specifically says that it is designed for a minimum
4.0.6.

In 4.1.0, the __FILE__ constant is set to the full path to the running
script starting from the root:
/home/mydirectory/public_html/mantis/script.php
In 4.0.6, the __FILE__ constant is set to only: /script.php

My question is regarding the history of __FILE__ between these releases
and whether there is any way to influence what is returned by __FILE__?
I could change the script for our purposes but before I even think of
that, I was wondering if there were PHP options that affect this behavior.

As far as upgrading the 4.0.6 to a higher release, I could ASK but the
server is not mine (or I'd likely be at the 4.3.x level.)

TIA,
Chris
