I'm still running Slackware 9.1 here. The latest released version of Slackware 
is 10.2, which comes with gcc 3.3.6. Requiring gcc 3.4 or 4.0 would mean it 
can't be used on the currently latest Slackware.

We do, in kdelibs/kxmlcore/.
gcc 3.3.6 is able to compile it, gcc 3.2.3 wasn't.
The only problem I had was the ctor/function declaration problem:
QBrush brush(QPixmap(...));
But this kind of problems can be fixed without problems.
