I find this surpricing...

in gtk-- I have the line:
   SIGNAL_SPEC(gint destroy_event(GdkEventAny*));

This line to NOT give a compile time error, it requires that there exists
a destroy_event virtual function.

I thought all the virtual functions in gtk+ has corresponding signal available
too:) (thats what gtk-- expects.. but of course that cannot be checked in
compile time as the signals in C are identified with string identified :)

Also there is no equivalent of plain destroy in gtk-- and it still seems to
compile... really odd :)

In my gtkwidget.h:
  gint (* destroy_event)           (GtkWidget          *widget,
                                    GdkEventAny        *event);
So, there exists destroy_event.
 
void       gtk_widget_destroy             (GtkWidget           *widget);
void       gtk_widget_destroyed           (GtkWidget           *widget,
                                           GtkWidget          **widget_pointer);

But there is. I have no idea what that virtual function does, but...
