**
** 5/2/94 Roman Hodek:
**   Added bi_atari part of the machine dependent union bi_un; for now it

** 26/7/96 Roman Zippel:
**   Renamed to setup.h; added some useful macros to allow gcc some
**   optimizations if possible.
** 5/10/96 Geert Uytterhoeven:
**   Redesign of the boot information structure; renamed to bootinfo.h again
