Last I checked this is still my server :)
I will move to php5 when my code is ready. I should make it in time in
any case.

Well, according to
http://www.php.net/manual/en/language.oop5.decon.php,
"For backwards compatibility, if PHP 5 cannot find a __construct()
function for a given class, it will search for the old-style
constructor function, by the name of the class."
In other words, the way I read this,

will never be called in php5 because __construct() exists, so it is
truly for backward compatibility.
