Good point. But is this really true?

Let's say application A links to two libraries (lib1 and lib2 which in 
the background link to Qt3 and Qt4).

A->lib1->Qt3
A->lib2->Qt4

I would think that the symbols would never conflict unless A includes 
the header files from Qt3 and Qt4 at the same time and links them directly.

But i just don't know...

I think that's very interesting, also for other projects like cross 
desktop components...
