I think it's fine to break SiC in this case.

Maybe we can have a  QT_RETURNED_CONST_TYPE macro that would be defined to 
"const" iff Q_COMPILER_MANGLES_RETURN_TYPE is defined, or nothing otherwise.
That way one would just write:

  QT_RETURNED_CONST_TYPE QPixmap pixmap() const;

and we would avoid any #ifdef
