Well, in fact it doesn't. The users will update their admin dir and
continue as usual, so that's not the point. I also think that the
current Qt apps do just fine with Qt 3 (didn't test it yet, didn't get
qt from rsync to compile yet), and the configure check should also work
although Werner Modenbach said on kdevelop that he has problems with it.
Harald, did you run some tests with a Qt 2 app using the current CVS and
Qt 3 ? I mean, does the configure check work and Makefiles get generated
plus does the app still compile and run ?

On the current problem, the obvious solution isn't a solution in this
case unfortunately, however it would be working around the problem
anyway instead of solving it.

Cheers,

Ralf
