Yep, I've discussed the situation with colleagues here at ARM.  The ARM 
ABI will not be changing in this respect: it will be using packed enums.

So the question now is whether NetBSD will be using the ARM ABI or 
something else.  What the something else is really doesn't matter, because 
as soon as one part has been abandoned you might as well consider 
everything open...

Of course, as soon as you abandon the common ABI you loose the ability to 
use other compilers, or pre-compiled libraries from other sources external 
to the project.
