	* include/std/std_streambuf.h (_M_mode): Move from here to
	filebuf and stringbuf.
	(~basic_streambuf()): Don't set _M_mode.
	(basic_streambuf()): Don't set _M_mode.
	* include/std/std_fstream.h (_M_mode): Move here, from streambuf.
	(~basic_filebuf()): Clean up.
	* include/bits/fstream.tcc (basic_filebuf()): Set _M_mode.
	* include/std/std_sstream.h (_M_mode): Move here, from streambuf.
