Hmm, no :-)

| There are two points:

|   features but there are few documents and descriptions about such hardware
|   except existing source code, so it's much more important to keep
|   intention of the original author in such MD code for future readers
|   than appeasing strict modern compilers by mechanical changes.
|   Furthermore, unexpected bugs could often slip in by such untested
|   mechanical changes and it makes harder to track problems in future.

Well, the code should be functionally equivalent and I doubt that anyone
has ever tested the atari installboot in a little endian machine. Or the
vax one on atari, which was the other bug that gcc found and could have
never worked...

How can I help? Is there an emulator?
