	* gfortran.h (gfc_get_typebound_proc): Removed as macro, now a function.
	(struct gfc_symtree): Moved `typebound' member inside union.
	(struct gfc_namespace): Add `tb_sym_root' as new symtree to sort out
	type-bound procedures there.
	(gfc_get_tbp_symtree): New procedure.
	* symbol.c (tentative_tbp_list): New global.
	(gfc_get_namespace): NULL new `tb_sym_root' member.
	(gfc_new_symtree): Removed initialization of `typebound' member.
	(gfc_undo_symbols): Process list of tentative tbp's.
	(gfc_commit_symbols): Ditto.
	(free_tb_tree): New method.
	(gfc_free_namespace): Call it.
	(gfc_get_typebound_proc): New method.
	(gfc_get_tbp_symtree): New method.
	(gfc_find_typebound_proc): Adapt to structural changes of gfc_symtree
	and gfc_namespace with regards to tbp's.
	* dump-parse-tree.c (show_typebound): Ditto.
	* primary.c (gfc_match_varspec): Ditto.  Don't reference tbp-symbol
	as it isn't a symbol any longer.
	* module.c (mio_typebound_symtree): Adapt to changes.
	(mio_typebound_proc): Ditto, create symtrees using `gfc_get_tbp_symtree'
	rather than `gfc_get_sym_tree'.
	(mio_f2k_derived): Ditto.
	* decl.c (match_procedure_in_type): Ditto.
	(gfc_match_generic): Ditto.  Don't reference tbp-symbol.
	* resolve.c (check_typebound_override): Adapt to changes.
	(resolve_typebound_generic): Ditto.
	(resolve_typebound_procedures): Ditto.
	(ensure_not_abstract_walker): Ditto.
	(ensure_not_abstract): Ditto.
	(resolve_typebound_procedure): Ditto, ignore erraneous symbols (for
	instance, through removed tentative ones).
	* gfc-internals.texi (Type-bound procedures): Document changes.

	* gfortran.dg/typebound_generic_1.f03: Change so that no error is
	expected on already erraneous symbol (renamed to fresh one).
