Thanks, looks like there's an -mmcu flag that gets passed to the compiler as well, telling it what chip the code is intended for. I think the answers I'm looking for are buried in those specifications. Gotta check them out, one of these days... > So Arduino programming is "just" C++ with additional libraries and an IDE. Considering that flag, I think it's something more (or less) than just plain C++...
