That clarifies some things. I was under the impression that it was 
decided that wxTNG was no longer the right course and that wx3 would 
just be more of the same as wx2 but with better unicode support.

I'll have a look and see how it works out.

About the STL support. I checked 2.8.5 and 2.9.0, and both work fine on 
OS X. I also checked 2.8.6 with MSVC 2008 beta2 and that seems to works 
as well. I was quite disappointed before because I did not get it to 
work on several occasions. I was starting to think that STL integration 
had a very low priority. I have already modified our tools so that they 
compile against versions of wxWidgets with STL support.
