Now that _Executor is non-recursive most subroutines no longer use their _Match_mode parameter (previously it was just passed to recursive _M_dfs calls). For now, just make them unnamed to avoid warnings. libstdc++-v3/ChangeLog: * include/bits/regex_executor.tcc (_Executor::_M_rep_once_more): Make unnused _Match_mode parameter unnamed. (_Executor::_M_handle_repeat): Likewise. (_Executor::_M_handle_subexpr_begin): Likewise. (_Executor::_M_handle_subexpr_end): Likewise. (_Executor::_M_handle_line_begin_assertion): Likewise. (_Executor::_M_handle_line_end_assertion): Likewise. (_Executor::_M_handle_match): Likewise. (_Executor::_M_handle_backref): Likewise. (_Executor::_M_handle_alternative): Likewise.
