	PR libfortran/44931
	* io/inquire.c (inquire_via_unit): Use ttyname to return actual device
	file name for stdin, stdout, and stderr.  If ttyname does not succeed
	fall back to default names for these units. Include string.h to allow
	using strlen function.
	* unix.c: Remove typedef of unix_stream structure, move to unix.h.
	* unix.h: Add typedef of unix_stream structure so that it is
	accessible to inquire.c.
