| ** 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. |
