spin2cpp warnings

I decided to update my spin2cpp clone to move to the latest code and I got the following warnings while compiling. Probably not a problem but I think Eric likes things to compile without warnings so I thought I'd post them.

Here is the compiler version info:

    David! Good to see you.

  • Thanks, Chip! I've actually been watching the forums pretty consistently but haven't had much time to actually participate. It sounds like the P2 is doing pretty well. I hope lots of people build it into successful products and that Parallax makes tons of money!
