The convention in other validator sources seems to be using Bool from:
native_client/src/shared/utils/types.h

And you'll "love" how it is defined

[khim, 2012/04/05 16:38:43]

Oh yeah. I especially love how Bool is unusable on non-MSVC systems. Ugh.
Separate clean fork for POSIX systems looks more and more feasible...

Done.
