So "ZERO_SIZE_OBJ_PTR" is the most correct form, and "ZERO_SIZE_PTR" is a convenient shortening. "ZERO_PTR" is too short and also confuses with NULL because NULL is a zero-value object, rather than a non-zero--value pointer to a zero-size object.
Like I said, I would prefer NIL of if absolutely need be NIL_PTR. NULL is a pointer that doesn't point anywhere valid -- NIL is a pointer that points to a zero sized object.
If I'd have a few small children around I'd show them the word ZERO_SIZE_PTR and make pictures of them bursting out in tears.
