If you only use the minimum level of c++. IE stay
away from templates, multiple inheritance and do
not use any of the standard c++ libraries you will
find it is extreamly portable. We do use all the above
and they work with Sun's, GNU's & MS's C++ compiler.
The days of C++ unportability if you stay away from
template specialisation are long gone. Most C++
compilers are starting to get that right now.

You should never nead to upcast if you have
designed your system correctly, this is what
virtual methods are for. It is true that for
performance reason it can be useful to upcast
but it is normal not neccessary.

There are other solution to there problems by using
the fact that a virtual method can return a different
type from the on on the base (can't remember the correct
name for this). But that is not really a discussion
for this list.
