That's great!

A good question. Our project is a heavy stress test for the whole tool 
chain and in an ideal world we'd track down every problem and solve it. 
In practice a combination that works after some little bit of tweaking 
dampens the "itch to scratch" motivation somewhat.

On Windows it is still MSVC2008, on OSX it is XCode3's gcc4.0, but on 
Linux anything recent is supposed to work.

Another interesting fact is, that the big warning-as-errors cleanup 
targeted gcc4.2, but as newer major versions understand the code flow 
better they provide better warnings. I agree with Pedro that we should 
look into llvm/clang in the future.

Of course there are known errors with some versions, e.g. or the problem we saw 
recently with gcc4.6 having some issues with STL in our bridges code. 
The former can be solved by upgrading gcc, the latter could be solved by 
making our code cleaner. Yet again it shows that using newer tools and 
attacking the problems that appear either improve the platform or our 
code base.
