      There are at least two places where 0 is used as a null pointer constant in macros, which invade user code and cannot be suppressed with -isystem. These should be changed to use Q_NULLPTR.

      1. default parameters in Q_OBJECT via QT_TR_FUNCTIONS, in qobjectdefs.h.
      2. QT_MESSAGELOG_FILE and QT_MESSAGELOG_FUNC in qlogging.h.
