Yes, I added a note in the README for this. There's no easy way around
this I think, since the various *int*_t typedefs depend on the platform
and architecture.

I tried in VS2010, and I believe VS2010 has some support for C++11, and
C++11 requires <cstdint>, and this file contains:

    #include <stdint.h>

But if you want to know, in VS2010 Express, the interesting part looks
like this:

    typedef signed char int8_t;
    typedef short int16_t;
    typedef int int32_t;

    typedef unsigned char uint8_t;
    typedef unsigned short uint16_t;
    typedef unsigned int uint32_t;

    typedef _Longlong int64_t;
    typedef _ULonglong uint64_t;

Nothing surprising about this.

Yes I will merge this and make a release today. Thanks to those changes,
I can now claim that the generated code is ANSI C, which should also
improve support for custom/old C compilers in the embedded world.
