/* WARNING: The following files are being included:
 *              <stdib.h>  -->  <endian.h>  -->  <bits/endian.h>
 * 
 *          endian.h defines the following constants as:
 *            #define __LITTLE_ENDIAN  and LITTLE_ENDIAN  as 1234
 *            #define    __BIG_ENDIAN  and    BIG_ENDIAN  as 4321
 *            #define    __PDP_ENDIAN  and    PDP_ENDIAN  as 3412
 * 
 *          bits/endian.h defines the constant BYTE_ORDER as:
 *              #define __BYTE_ORDER as __LITTLE_ENDIAN
 * 
 *          endian.h then sets the following constants
 *          (if __USE_BSD is set, which seems to be true):
 *            # define LITTLE_ENDIAN    __LITTLE_ENDIAN
 *            # define BIG_ENDIAN       __BIG_ENDIAN
 *            # define PDP_ENDIAN       __PDP_ENDIAN
 *            # define BYTE_ORDER       __BYTE_ORDER
 * 
 *         CONCLUSION:
 *           The bacnet library uses the BIG_ENDIAN constant (set to 0, or anything <>0)
 *           to indicate whether we are compiling on a little or big endian platform.
 *           However, <stdlib.h> is defining this same constant as '4321' !!!
 *           The decision to use BIG_ENDIAN as the constant is a unfortunate 
 *           on the part of the bacnet coders, but we live with it for now...
 *           We simply start off by undefining the BIG_ENDIAN constant, and carry
 *           on from there!
