        (current_file_function_operand): Likewise.
        (small_data_operand): Likewise for parameters `op' and `mode' but
        only when !TARGET_ELF.
        (init_cumulative_args): Mark parameters `libname' with
        ATTRIBUTE_UNUSED.
        (function_arg_pass_by_reference): Likewise for parameters `cum',
        `mode' and `named'.
        (expand_builtin_saveregs): Likewise for parameter `args'.

        (branch_comparison_operator): Likewise.
        (secondary_reload_class): Likewise.
        (print_operand): Add parentheses around & operation.
        (output_prolog): Mark parameter `size' with ATTRIBUTE_UNUSED.
        (output_epilog): Likewise.  Cast argument to fprintf to int.
        (rs6000_adjust_cost): Mark parameter `dep_insn' with ATTRIBUTE_UNUSED.
        (rs6000_valid_decl_attribute_p): Likewise for parameters `decl',

        * rs6000.h (RTX_COSTS): Add parentheses around & operation.
        (toc_section, private_data_section, trap_comparison_operator): Add
        prototypes.
        * dbxout.h (dbxout_parms, dbxout_reg_parms, dbxout_syms): Add
        prototypes.
        * xcoffout.c: Include toplev.h, outout.h and dbxout.h.
