Bug in 3.3.1 cc: void cast of struct.

[Gary S. Moss VLD/VMB <moss>]

I intend to call this in to the Hotline, but it is a lot easier to provide
test cases electronically, so here goes:

main()
        {       static struct coord
                        {
                        double x, y, z;
                        }
                a = { 1.0, 2.0, 3.0 }, b;
                (void)(b = a);
        }
$ make voidcast
	cc -O voidcast.c  -o voidcast
ccom: Error: voidcast.c, line 7: Cast of struct/union is illegal
                (void)(b = a);
      -----------------------^
*** Error code 1

I have it on authority from one of the members (Doug Gwyn) of the ANSI C (X3J11)
standardization committee that any type may be cast to void.  Forget why I want
to do this, the example is a simplification.  This works fine under the IRIX
3.2.2 version of cc, but not under 3.3.1.

Please, can we have a fix soon?
Thanks,
