I see. Can't remember exactly where we do that off the top of my head, 
but I guess we do somewhere. :) The code works on both VC++ (7.1 and 
8.0) and GCC 3.3 so that's why we haven't noticed I guess. I'll look 
into that tomorrow, and fix it where applicable.

I'm pretty sure it is an error. Now that you mention it, I have seen the 
explaination for that somewhere too. I'm not sure where we actally do 
that though, but I'll look into this tomorrow as well.

Guess I should have mentioned this. Sorry. The code is using Boost 1.32 
- release version.
