Is there any chance that these macros will find their way into Qt4? I don't 
mean that they should be used by Qt itself everywhere (or at all), but 
providing them would allow an easy forward-compatible way of introducing this 
stuff. That may not really help for KDE (or we need to require 4.8.3 or need to 
ship them ourself) but for other stuff out there this would be an improvement 
that you basically get for free.
