But I messed up Qt3Support ;-((. Please find a new patch attached which 
corrects QT_COMPAT_LIB to QT_QT3SUPPORT_LIB.
Sorry, but I have only one Qt3Support based "simple" example ...

It's not mine, the Qt sources work with them. And no, they include the moc'ed 
file in the _source_ , some files even include both (moc'ed cpp and moc'ed 
header ) . Otherwise, it would be quite hard not to violate the ODR or some 
other c++ contraints..

Good to hear that it is only backwards compatibility in this case.
But don't push this, it would be nice to replace V1 first.

I'll put the thing together and send it via private email.
