+** Created 09/29/92 by Greg Harp
+**
+** 5/2/94 Roman Hodek:
+**   Added bi_atari part of the machine dependent union bi_un; for now it
+**   contains just a model field to distinguish between TT and Falcon.
+** 26/7/96 Roman Zippel:
+**   Renamed to setup.h; added some useful macros to allow gcc some
+**   optimizations if possible.
