Some time ago I had a similar problem (I think). I would like to compile a
program with Qt, but using the gcc3.x (any different of the official).
There's a recursive question.
Gcc3.2 has different ABI that Gcc2.95, so they are incompatible. You can
compile and link a program with a library with 3.2 but you need that library
compiled with 3.2.
So if you want to compile a kde program with 3.2, you need to have kdelibs,
etc, compiled with 3.2, if you do that you will need to compile qt with 3.2.
All the C++ source will need compile with 3.2. I have said all C++, because
the ABI have been changed for all the C++ layer (not yet for the C).
Therefore, or you wait till debian was fully with 3.2, or you have to compile
(as I tried to do) all the C++ source with 3.2.
Best regards.
