Tim Janik 0f0d9509c0 `const' fixups. 
Thu Sep  3 07:16:54 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkctree.h:
        * gtk/gtkctree.c: `const' fixups.

        * gtk/gtkclist.h:
        * gtk/gtkclist.c: `const' fixups and some coding style adaptions.

        * gtk/gtkctree.c (gtk_ctree_insert_node): don't dereference *text
        if it is passed as NULL.
