CHECK-STRUCT-TYPE

Here are some defstructs. Below is a backtrace in which 
check-struct-type complains that a c-variable instance is not a 
c-stream. Aside from the c-stream defstruct, the source contains no 
references to c-streams--they were a new-fangled cell I abandoned early on.

The code which fails is:

(defun c-install (self sn c)
   "Install cell C in slot named SN of instance SELF"
   (assert (typep c 'cell))
   (setf
    (c-model c) self
    (c-slot-spec c) sn
    (md-slot-cell self sn) c
    (slot-value self sn) (when (typep c 'c-variable)
                           (c-value c))))

This is a terribly inadequate bug report, thrown out FWIW because I am 
just going to try the same now on CLisp, and getting Cells to work on 
CormanLisp is not an immediate priority. I understand if no one follows 
up on this because the bug report is so shoddy, but I offer it anyway on 
the off chance some bug in and around (I guess) the setf logic jumps out 
at you.
