Oops, nobody told Allen:

 https://github.com/KDAB/GammaRay/commit/44ac33d970e

I think this affects far more code than you seem to think it affects. 

What *should* Allen do now? What macro works for multiple versions of Qt? 
Why should everyone define such a macro themselves in their code? How about 
contributing it back to qglobal.h? What would it be called? And to bring 
this full circle, how about swapping the semantic of the old and new macros?

I'm sure you considered not making the SIC change and creating a new macro 
instead. Why did you decide for the SIC?

Thanks,

Steve.
