For the googlecode version yes, it is standalone CPP. I just haven't gotten around to checking in the 0.80 CPP file yet. Had to be that way for a more reliable pre-built product that didn't have me chasing my tail for every cpu or OS imaginable, or when the next version of arduino breaks the program (like what happened 6 hours after I announced it's release
), or when someone has a problem with 64 bit linux or mac OS that I shouldn't have to care about
If there's any doubt left though, I'm done dealing with the arduino framework. Arduino.cc, and probably a few people here, have plenty of good tips though.
Edit: avrfreaks.net is an awesome non-arduino specific avr resource as well.
