        * decl.c (match_data_constant, match_data_constant,
        * variable_decl,
        gfc_match_decl_type_spec, access_attr_decl,
        check_extended_derived_type, gfc_match_derived_decl,
        gfc_match_derived_decl, gfc_match_derived_decl) Modified to deal
        with DT constructors.
        * gfortran.h (gfc_find_dt_in_generic,
        gfc_convert_to_structure_constructor): New function prototypes.
        * interface.c (check_interface0, check_interface1,
        gfc_search_interface): Ignore DT constructors in generic list.
        * match.h (gfc_match_structure_constructor): Update prototype.
        * match.c (match_derived_type_spec): Ensure that one uses the DT
        not the generic function.
        * module.c (MOD_VERSION): Bump.
        (dt_lower_string, dt_upper_string): New functions.
        (find_use_name_n, find_use_operator, compare_true_names,
        find_true_name, add_true_name, fix_mio_expr, load_needed,
        read_module, write_dt_extensions, write_symbol): Changes to deal with
        different symtree vs. sym names.
        (create_derived_type): Create also generic procedure.
        * parse.c (gfc_fixup_sibling_symbols): Don't regard DT and
        * generic
        function as the same.
        * primary.c (gfc_convert_to_structure_constructor): New
        * function.
        (gfc_match_structure_constructor): Restructured; calls
        gfc_convert_to_structure_constructor.
        (build_actual_constructor, gfc_match_rvalue): Update for DT generic
        functions.
        * resolve.c (resolve_formal_arglist, resolve_structure_cons,
        is_illegal_recursion, resolve_generic_f, resolve_variable,
        resolve_fl_variable_derived, resolve_fl_derived0,
        resolve_symbol): Handle DT and DT generic constructors.
        * symbol.c (gfc_use_derived, gfc_undo_symbols,
        gen_special_c_interop_ptr, gen_cptr_param,
        generate_isocbinding_symbol, gfc_get_derived_super_type): Handle
        derived-types, which are hidden in the generic type.
        (gfc_find_dt_in_generic): New function
        * trans-array.c (gfc_conv_array_initializer): Replace
        * FL_PARAMETER
        expr by actual value.
        * trans-decl.c (gfc_get_module_backend_decl,
        * gfc_trans_use_stmts):
        Ensure that we use the DT and not the generic function.
        * trans-types.c (gfc_get_derived_type): Ensure that we use the
        * DT
        and not the generic procedure.
