regarding the value of the array assignment expression, this
made me wonder what the compiler does for structure assignments.
i tried this (4.1a BSD cc):

    main()
    {
	struct { int x, y, z ; } a, b;

	if ((a = b) != 0)
	    ;
    }

and got the diagnostic "operands of != have incompatible types".
(btw, this compiler generated a movc3 instruction for the actual copy.)
