Make PowerPhlogger 2.2.5 working on PHP 5

PowerPhlogger 2.2.5 is a nice script for tracking your site visitor on your own. I have been using PowerPhlogger 2.2.5 for a long time. But it is a dead project and not updated anymore since 11/01/2003. And now it is completely dead because it is not working on PHP 5 as it has coded on PHP 4.
You can make it work on PHP 5 changing some code;
on login.php just modify line 49 and 50 and replace $HTTP_SESSION_VARS
with $_SESSION. It is all!
Happy tracking your visitors..
