        * link.cc: Added variant of create_error_method that
        will not complain about unused parameter if compiled with
        USE_LIBFFI not being defined.
        (_Jv_Linker::find_field_helper): Fixed indentation.
        (_Jv_Linker::create_error_method): Fixed indentation.
        (_Jv_Linker::link_symbol_table): Fixed indentation.
