        * gdk/gdkcursor.h (struct _GdkCursor): s/refcount/ref_count/.
        * gdk/x11/gdkcursor-x11.c (gdk_cursor_new_from_pixmap):
        * gdk/x11/gdkcursor-x11.c (_gdk_cursor_destroy):
        * gdk/gdkcursor.c (gdk_cursor_ref): insert assertments for the
        parameters given and cursor->ref_count. coding style fixups.

        * gtk/gtksocket.c (gtk_socket_class_init): parent class is GtkContainer,
        not GtkWidget.

        * gtk/*.h: applied patch from Mathieu Lacage <lacage@email.enst.fr> to
        fix up widget macros and add _GET_CLASS() variant.

        * gtk/*.c: some GtkType fixups.
