+GNU C++ compiler gives a warning for any class whose destructor is private
+unless it has a friend. This warning may sometimes be useful but it doesn't
+make sense for reference counted class which always delete themselves (hence
+destructor should be private) but don't necessarily have any friends, so this
+macro is provided to disable the warning in such case. The \arg{name} parameter
+should be the name of the class but is only used to construct a unique friend
+class name internally. Example of using the macro:
+
+\begin{verbatim}
+    class RefCounted
+    {
+    public:
+        RefCounted() { m_nRef = 1; }
+        void IncRef() { m_nRef++ ; }
+        void DecRef() { if ( !--m_nRef ) delete this; }
+
+    private:
+        ~RefCounted() { }
+
+        wxSUPPRESS_GCC_PRIVATE_DTOR(RefCounted)
+    };
+\end{verbatim}
