Actually, that's a good question. I don't know whether the order of
the non-virtual public and protected functions and variables
matters. (All I know from BC is from that newsletter article.) When
I made the Midi Kit classes binary compatible, I simply took the Be
headers and left the public and protected stuff alone.

AFAIK, you can safely add new variables, as long as the sizeof()
stays the same. Whether it is smart to add stuff to the public and
protected sections is another thing, because that means you are
changing the class' API...
