        * gtk/gtkaccelerator.h (struct _GtkAcceleratorTable): changed ref_count
                field to be of type guint.
                        * gtk/gtkaccelerator.c (gtk_accelerator_table_unref): added check for
                                ref_count>0;
                                        (gtk_accelerator_table_install): keep a per object list of accelerator
                                                tables that refer to this object.
                                                        (gtk_accelerator_table_remove): remove the accelerator table from the
                                                                per object list.
                                                                        (gtk_accelerator_table_clean): warn if there are any object references
                                                                                left in an accelerator table upon destruction.
                                                                                        (gtk_accelerator_tables_delete): new function to delete object
                                                                                                references from the accelerator tables associated with this object.

                                                                                                        * gtk/gtkwidget.c (gtk_widget_class_init): changed emission of
                                                                                                                GtkWidget::install_accelerator to GTK_RUN_LAST so the installation
                                                                                                                        of an accelerator can be prevented by gtk_signal_emit_stop().
                                                                                                                                (gtk_widget_real_destroy): call gtk_accelerator_tables_delete (),
                                                                                                                                        so there are no stale pointers in accelerator tables left.



this change is binary compatible, so just touch gtkaccelerator.h -r gtkwidget.h
