The sentences were not affirmative because I didn't confirm the
intention of the author as of the above message.  But with his private
mail, I could do after that.  The patch actually does not break the
case GC_LISP_OBJECT_ALIGNMENT < sizeof Lisp_Object, but fixes it when
the stack grows in the decreasing direction.
