Our target is a special 68000 board. I don't know the details, since
another team actually deals with this thing, but I understand that
the compiler or parts of it has been rewritten for this particular target.
Also, there is an Ada_Connect package that allows us to talk to the
68000 over the bus. The team told me that when this package  is used,
Adaprobe doesn't run. 

Alsys says: "We'll fix it". It's been saying this for over a year now.
It's still not fixed, so in the meantime we're doing what we can.

I'm aware of that. But how do you 'step' with a real debugger? Doesn't
that also work with added code between every source line?

Thanks, I'll look into that.
