- Why? The idea is basically to keep the old header files for compatibility,
- and to use the new standardized header files for new programs.

- This is exactly what I don't want. Let's have the same header files, no matter
- what compiler is used, what architecture is used or whether MiNT is used
- (should be used all the time :-).

- If this is the reason, this should be done with all structures. However,
- I still prefer to use the original names defined by Atari.
