Thanks for that Pascal. The only sane way to approach the issue IMHO is 
to accept that this may and probably will break backward compatibility 
(not even think about supporting 5.1 or 5.2) and just consider whether 
that break is justified (hint: it is).

Not that I have the skills to do the port, just the time and 
stubbornness to attempt it. :-)
