No, I'm talking about the case when we can't us __attribute__ ((aligned (X))).
Because if we can, there is no problem at all:

#define _GC_ALIGNED_ __attribute__ ((aligned (GCALIGNMENT)))

struct _GC_ALIGNED_ Lisp_Cons
  {
    ...;
  };

#define scoped_cons(car, cdr)                                   \
  make_lisp_ptr (&((struct Lisp_Cons) { car, { cdr } }), Lisp_Cons)
