you are right. My statement was not precise enough: Adding a parameter
to the existing function would be BiC, adding an overload "void
QFutureWatcher::waitForFinished(int timeout);" is BC but would be SiC
because it makes function pointers ambiguous - at least I think so.
About the latter I am also not sure, if that would be a problem since
I am not familiar with the exact promises Qt makes about SC.
