 * value for all data types (int, long, ...).   The result is an
 * unsigned long and must be cast to any desired pointer type.
 *
 * _ALIGNED_POINTER is a boolean macro that checks whether an address
 * is valid to fetch data elements of type t from on this architecture.
 * This does not reflect the optimal alignment, just the possibility
 * (within reasonable limits).
