Yes, thanks for the clarification.

FreeBSD 10 doesn't have int8_t in /usr/includes/stdint.h.  I know we 
used to avoid using C99 things like that, but do we compile in such a 
way to make the compiler not work with C99 code?

That's a good question and I don't have a Windows development 
environment right now to test removing it.
