ESUG Summertalk succeeded to get a really smart guy helping there.
Mathieu is regularly working and improving the new compiler. Thanks  
So ESUG spent 1500 Euros (this is not a lot but we do it) to go  
slowly and
make sure that we could get a new compiler in a better shape.

The squeakfoundation is supporting the Summertalk effort.

Of course, if the foundation really wanted to collect some money for  
improving the
system this would help... But you know why I left it.
