You might want to read "Multiple Inheritance for C++" by Bjarne
Stroustrup (Proceeding sof the EEUG Spring Conference, Helsinki,
May, 1987).

Multiple inheritance is difficult to implement, but once someone
else has written the compiler, application programming is very easy.
The Stroustrup paper discusses the implementation in C++.

Multiple inheritance has many applications in the graphics world.  For
example, your window system may have graphics window, text window, and
scrollable window classes.  An application programmer may want to
create a new class with properties from all three.  Without multiple
inheritance, this is very messy.  Several of the popular user interface
toolkits (e.g., X Toolkit, Andrew Toolkit) have this problem with
single inheritance and can't wait for C++ with multiple inheritance.
