I have the same problem and any suggestions on how to solve this would
be much appreciated.

Currently I'm wrapping all boost includes that cause the problem this like:

#pragma warning(push)
#pragma warning(disable: 4005)
#include <boost/spirit.hpp>
#include <boost/spirit/phoenix.hpp>
#pragma warning(pop)

But it's not pretty.
