Mu Ultra 10 is looking at me with sad eyes, and I try to comfort it:
"I know you have lots more registers than that stupid x86, I don't think
Win32 is going to be such a very strict requirement?"

Is L4 haveing Win32 binary 'compatibility' as a goal?

Or is it just a sort of 'we might try, but if no go, no problem' kind of
thing?
