Not part of this chhange, but shouldn't this be _MSC_VER instead of _WIN32?

[Cutch, 2013/06/03 14:52:21]

I believe you're correct. It's MSVC that lacks support for stdbool not the WIN32
platform.

[Ivan Posva, 2013/06/03 15:42:52]

As you can see below with all of the other int types, it is assumed that _WIN32
and !__CYGWIN__ expects a non-C99 based compiler such as MSVC.

__CYGWIN__ is not supported at the moment and is caught a couple of lines
further up.

So I am leaving this as it is for now. If we really get somebody trying to build
on Windows with some other toolchain than MSVC, then we can address it then.
