I think Qt uses a method that prevent backward compatibility breaking,
by having
two interfaces for each class. One is the public one that do not
change, and that contains a pointer to the private one, where changes
goes on. I think this is a well known technique but I cannot find any
reference on the web about it. Their code is open source so you might
have a look at it. Another technique is to use C wrapper that does
stuff with your C++ objects but you lose the power of C++...
