#include <boost/cstdint.hpp>
#include <cstdint>

[Steven Watanabe]

Boost.Config needs to define BOOST_HAS_STDINT_H.

[John Maddock]

(In [62082]) Add support for <cstdint> in VC10. Fixes #4182.

There is another problem with this fix when intsafe.h from the windows sdk is included. Preventing BOOST_HAS_STDINT_H to get defined removes the warnings.

This is nothing to do with us - the fact that two Microsoft headers conflict with each other is their issue not ours - sorry to be so blunt, but we should be able to use <stdint.h> without worrying what other headers may have been included.

John Maddock.

True. Do you have a snippet to reproduce this issue so it can be reported to MS?

[John Maddock]

This:

#include <intsafe.h>
#include <stdint.h>
