Well, it is specific to Qt. Q_MOC_RUN is the designed workaround for missing 
c++ support in the moc.

Well, in the aforementioned thread the TypeTraits maintainer came to the 
correct conclusion that this is definetely a moc bug. It simply fails to parse 
several type_traits header which are valid c++.
So please file a bug at Qt's bugtracker for this. It would be nice if you could 
post the ticket number here so we can track this.

Yours,

Jürgen
