sorry - hit sent too early.

The definition of said macro is:


#define Q_OBJECT_CHECK \
    template <typename T> inline void qt_check_for_QOBJECT_macro(const T 
&_q_argument) const \
    { int i = qYouForgotTheQ_OBJECT_Macro(this, &_q_argument); i = i; }

see the "i = i". Is that just to ensure it's not marked as unused? Could 
something be done about it? Maybe the (void) i "trick" that Q_UNUSED applies?
