Thanks Marcel for helping me out here, but in the meantime I also read this:

http://techbase.kde.org/Policies/Binary_Compatibility_Issues_With_C++

saying "In the KDE project, we will provide binary compatibility within the 
life-span of a major release for the core libraries (kdelibs kdepimlibs)."

This means to me within 4.4.x there have to be ABI compatibility and for 4.x 
there should be at least API compability where function signatures can change. 

I made some changes to libkdcraw for 4.5. For ABI compability I have to revert 
them and add duplicates with new signatures. Is this really needed?
