Missing a flag?

[Thijs Schreijer <thijs@...>]

General question;
While trying to build my (Windows) DarkSideSync library on Ubuntu, I get the errors below. Basically BOOL is missing, which is defined on Windows. I know that C does not have a Boolean type, but in this case, should I be adding some flag or other element to the rockspec (and if so, which one) ?
Or should I just define my own BOOL? (and TRUE and FALSE along with it)

Thx!
