 * Routines for Little Endian and Big Endian Systems
 * Library version
 *
 * Version 0.4, 2003-09-08
 * Author: Björn Berg, clergyman@gmx.de
 *
 * History:
 * 2003-09-08   berg    changes in u_int types, adapted to different system
 *                                              standards
 * 2003-04-18   berg    endian.h splitted to endian.h and endian.c
 *
 * 2003-02-16   jones   the #ifndef inclusion guard only protected the #defines
 *                                              where it really needs to protect the whole file. Just
 *                                              moved the #endif to the end of the file.
 * 2003-02-09   jones   improved IsBigEndian function
 *                                              changes in rotate4b
 * 2003-02-01   berg    rotate2b / rotate4b added
 * 2002-12-12   berg    first implementation
