It was my impression this was the whole point of Qt: A single platform 
independent API which is a wrapper around different code paths for each 
operating system.. If we had to split all platform specific code in to a 
"support" library, it would be a very large library indeed. I think what 
they mean is that functions/methods within the API which can only be 
USED from a specific OS (fromWinHBITMAP and fromWinHICON for example) 
should be in an OS support library. Remember the main API is supposed to 
be the same on all platforms.
