I don't know what the ANSI standard says, but K&R (rev 1) does leave some
reasonable doubt w.r.t. this functionality being *required*.  From page 121:

	"This implies that structures may not be assigned to or copied as a
	unit, and that they can not be passed to or returned from functions.
	(These restrictions will be removed in forthcoming versions.)"

SUN supports struct to struct assignments-- I would advise that
you check on your machine with your test program (and some modifications
to verify the results).
