 * PROGRAMMER "BAHN, William"
 * TITLE      "Integer Storage Size Type Definitions"
 * CREATED    06 FEB 07
 * MODIFIED   06 FEB 07
 * FILENAME   "bytes.h"
 * =======================================================================
 * GENERAL DESCRIPTION
 *
 * This file contains type definitions so that porting from one processor
 * to another is simpler.
 * =======================================================================
 * SIZE DEFINITIONS
 *
 * The following definitions are used:
 * 
 *   SIZE   UNSIGNED   SIGNED
 *   8-bit    BYTE     SBYTE
 *  16-bit    WORD     SWORD
 *  32-bit    DWORD    SDWORD
 *  64-bit    QWORD    SQWORD (not available on most systems)
 *
 * =======================================================================
 * To Verify Sizes
 * 
 * Use the VerifySIZES() function passing the largest integer size, in 
 * bits, that is of interest.
 *
 * The function returns TRUE if conflicts are found.
 *
 * If an argument of 0 is used, then the return value has a bit set for
 * each type definition that didn't verify, starting with the shortest
 * length in the LSB.
 *
 * Example - you are interested only in integer sizes up to 32-bits.
 *
 * VerifySIZES(32) or VerifySIZES(BITSinDWORD);
 *

 * Normal definitions
 *
 * This the only section that should need to be changed.
 *
 * Determine which integer type is the correct number of bits and update
 * the following list. Do not worry about signed/unsigned.
 *
 * It is not recommended that you actually use these definitions in your
 * code - they are simply used in the following type definitions.
