        * trans-array.c (gfc_trans_array_constructor_value): If the
        iterator variable does not have a backend_decl, use a local
        temporary.
        (get_elemental_fcn_charlen): New function to map the character
        length of an elemental function onto its actual arglist.
        (gfc_conv_expr_descriptor): Call the above so that the size of
        the temporary can be evaluated.
        * trans-expr.c : Include arith.h and change prototype of
        gfc_apply_interface_mapping_to_expr to return void.  Change all
        references to gfc_apply_interface_mapping_to_expr accordingly.
        (gfc_free_interface_mapping): Free the 'expr' field.
        (gfc_add_interface_mapping): Add an argument for the actual
        argument expression. This is copied to the 'expr' field of the
        mapping.  Only stabilize the backend_decl if the se is present.
        Copy the character length expression and only add it's backend
        declaration if se is present.  Return without working on the
        backend declaration for the new symbol if se is not present.
        (gfc_map_intrinsic_function) : To simplify intrinsics 'len',
        'size', 'ubound' and 'lbound' and then to map the result.
        (gfc_map_fcn_formal_to_actual): Performs the formal to actual
        mapping for the case of a function found in a specification
        expression in the interface being mapped.
        (gfc_apply_interface_mapping_to_ref): Remove seen_result and
        all its references. Remove the inline simplification of LEN
        and call gfc_map_intrinsic_function instead.  Change the
        order of mapping of the actual arguments and simplifying
        intrinsic functions.  Finally, if a function maps to an
        actual argument, call gfc_map_fcn_formal_to_actual.
        (gfc_conv_function_call): Add 'e' to the call to
        gfc_add_interface_mapping.
        * dump-parse-tree.c (gfc_show_symbol_n): New function for
        diagnostic purposes.
        * gfortran.h : Add prototype for gfc_show_symbol_n.
        * trans.h : Add 'expr' field to gfc_add_interface_mapping.
        Add 'expr' to prototype for gfc_show_symbol_n.
        * resolve.c (resolve_generic_f0): Set specific function as
        referenced.
