* LITTLE_ENDIAN and that the two (BYTE_ORDER and LITTLE_ENDIAN) are

*
|
||||
* #define LITTLE_ENDIAN 1234
|
||||
* #define BIG_ENDIAN 4321
|

*
|
||||
* And for little-endian machines, add:
|
||||
*
|
||||
* #define BYTE_ORDER LITTLE_ENDIAN
|
||||
*
|
||||
* Or for big-endian machines:
|
||||
*
|
||||
* #define BYTE_ORDER BIG_ENDIAN
|
||||
*
|
||||
* The FreeBSD machine this was written on defines BYTE_ORDER
|
