        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/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.
