Yes, using the same Gtk example, the way you’d forward declare GtkLabel without including gtklabel.h in your header would be:

    struct _GtkLabel;
    typedef struct _GtkLabel GtkLabel;
    // Use GtkLabel* in declarations


Why are you complicating things? Struct and Unions are different namespaces for a reason.

    typedef struct GtkLabel GtkLabel;
works just fine.


I’m simply stating how actual Gtk is written:

True, thanks then. As far as I see it they don't even use the struct in the implementation, so I guess it makes some sense.
