Yes, we are. The original code did, and Alex found it too complicated
for the immediate build fix when I suggested it. As you can see, I've
already split up into AREG0 and non #ifdef paths because it got too
unreadable when having one line with multiple or'ed #if conditions.
Optimizations we can still do when the build is restored.
