	PR fortran/23815
	* io/file_pos.c (unformatted_backspace):  If flags.convert
	does not equal CONVERT_NATIVE, reverse the record marker.
	* io/open.c:  Add convert_opt[].
	(st_open):  If no convert option is given, set CONVERT_NATIVE.
	If CONVERT_BIG or CONVERT_LITTLE are given, set flags.convert to
	CONVERT_NATIVE or CONVERT_SWAP (depending on wether we have
	a big- or little-endian system).
	* io/transfer.c (unformatted_read):  Remove unused attribute
	from arguments.
	If we need to reverse
	bytes, break up large transfers into a loop.  Split complex
	numbers into its two parts.
	(unformatted_write):  Likewise.

	reverse the record marker.
