- * @brief Alignment type.
- *
- * The value of _Align is a default-alignment which shall be the
- * most stringent alignment requirement for any C++ object type
- * whose size is no greater than _Len (3.9). The member typedef
- * type shall be a POD type suitable for use as uninitialized
- * storage for any object whose size is at most _Len and whose
- * alignment is a divisor of _Align.
