	PR fortran/28601
	PR fortran/28630
	* gfortran.h : Eliminate gfc_dt_list structure and reference
	to it in gfc_namespace.
	* resolve.c (resolve_fl_derived): Remove the building of the
	list of derived types for the current namespace.
	* symbol.c (find_renamed_type): New function to find renamed
	derived types by symbol name rather than symtree name.
	(gfc_use_derived): Search parent namespace for identical
	derived type and use it, even if local version is complete,
	except in interface bodies. Ensure that renamed derived types
	are found by call to find_renamed_type. Recurse for derived
	type components.
	(gfc_free_dt_list): Remove.
	(gfc_free_namespace): Remove call to previous.
	* trans-types.c (copy_dt_decls_ifequal): Remove.
	(gfc_get_derived_type): Remove all the paraphenalia for
	association of derived types, including calls to previous.
	* match.c (gfc_match_allocate): Call gfc_use_derived to
	associate any derived types that are being allocated.

	PR fortran/20886
	* resolve.c (resolve_actual_arglist): The passing of
	a generic procedure name as an actual argument is an
	error.

	PR fortran/28735
	* resolve.c (resolve_variable): Check for a symtree before
	resolving references.

	PR fortran/28762
	* primary.c (match_variable): Return MATCH_NO if the symbol
	is that of the program.

	PR fortran/28425
	* trans-expr.c (gfc_trans_subcomponent_assign): Translate
	derived type component expressions other than another derived
	type constructor.

	PR fortran/28496
	* expr.c (find_array_section): Correct errors in
	the handling of a missing start value for the
	index triplet in an array reference.

	PR fortran/18111
	* trans-decl.c (gfc_build_dummy_array_decl): Before resetting
	reference to backend_decl, set it DECL_ARTIFICIAL.
	(gfc_get_symbol_decl): Likewise for original dummy decl, when
	a copy is made of an array.
	(create_function_arglist): Likewise for the _entry paramter
	in entry_masters.
	(build_entry_thunks): Likewise for dummies in entry thunks.

	PR fortran/28600
	* trans-decl.c (gfc_get_symbol_decl): Ensure that the
	DECL_CONTEXT of the length of a character dummy is the
	same as that of the symbol declaration.

	PR fortran/28771
	* decl.c (add_init_expr_to_sym): Remove setting of charlen for
	an initializer of an assumed charlen variable.

	PR fortran/28660
	* trans-decl.c (generate_expr_decls): New function.
	(generate_dependency_declarations): New function.
	(generate_local_decl): Call previous if not either a dummy or
	a declaration in an entry master.
