At this point, I think the only regular user of the old simulavr is the 
avr-libc regression tests. Since we control the scripts that run it, we can 
change it as necessary.

I have not heard of the old simulavr being used widely in the field. I don't 
think we have to worry so much about backwards compatibility that it should 
hamper us from doing what's right.

If simulavrxx is going to be developed to the point that it will subsume the 
old simulavr and avrtest, then I would like to change the name of it to just 
plain "simulavr" to avoid confusion. The "xx" part was just to show that it is 
developed in a C++ code base, but that doesn't matter to our end users. I would 
also like to see a release version of 1.0 *even if it's not perfect*.
