/** Machine and/or Compiler Specifics
 *
 *  BIG_ENDIAN specifies the byte and word ordering convention.
 *  If TRUE (1), the target implementation is big-endian;
 *  otherwise, FALSE (0) means little-endian.
 *
 *  UNALIGNED_DATA_ACCESS_OK specifies whether unaligned data
 *  accesses are fault-free.  If TRUE (1), reading or writing an
 *  object that is not aligned on its natural boundary will not
 *  cause a fault (but could reduce performance); otherwise,
 *  FALSE (0) means that an unaligned access will cause a fault.
 *
 *  PRAGMA_PACK_ENABLE and PRAGMA_PACK_DISABLE are
 *  compiler-specific preprocessor tokens that control structure
 *  packing.
 *
 *  Note: The widths connoted byte these typedef's may not be
 *        exactly represented on some architectures (e.g., some
 *        DSP's have 24-bit integers).
