	(gfc_resolve_open):  Likewise.
	(gfc_free_inquire):  Likewise.
	(match_inquire_element):  Likewise.
	* dump-parse-tree.c (gfc_show_code_node):  Add
	convet for open and inquire.
	gfortran.h: Add convert to gfc_open and gfc_inquire.
	* trans-io.c (gfc_trans_open):  Add convert.

	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.
	(us_read):  If flags.convert does not equal CONVERT_NATIVE,
	reverse the record marker.
	(next_record_w): Likewise.
	(reverse_memcpy):  New function.
	* io/inquire.c (inquire_via_unit):  Implement convert.
	* io/io.h (top level):  Add enum unit_convert.
	Add convert to st_parameter_open and st_parameter_inquire.
	Define IOPARM_OPEN_HAS_CONVERT and IOPARM_INQUIRE_HAS_CONVERT.
	Increase padding for st_parameter_dt.
	Declare reverse_memcpy().
