* gdk/x11/gdkproperty-x11.c: (gdk_property_get): Fix wrong type in g_new -- bug if sizeof (GtkAtom) != sizeof (GtkAtom *). * gdk/x11/gdkwindow-x11.c: (create_moveresize_window): FALSE -> NULL * gtk/gtkaccellabel.c: (gtk_accel_label_refetch): Remove unused local. * gtk/gtklistitem.c: (gtk_list_item_expose): Remove unused local. * gtk/gtktextiter.c: (_gtk_text_iter_backward_indexable_segment): Restructure loop to get rid of uninitialized variable warning. Also gives a tiny efficiency gain.
