12469	BOOST_MPL_PRINT_HPP generates error: negative integral constant converted to unsigned type	anonymous	Aleksey Gurtovoy	"Hi, serialization in win32 generates compile error in VS2015. The error is: 
c:\program files\boost\boost_1_61_0\boost\mpl\print.hpp(52): error C4308: negative integral constant converted to unsigned type

{{{
#elif defined(BOOST_MSVC)
    enum { n = sizeof(T) + -1 };
#elif defined(__MWERKS__)
}}}

And ultimately this was triggered by:


{{{
private:
	// the range of the output hashed variable
	size_t mWidth;
	size_t mPrime;
	size_t mKindependent;

	std::shared_ptr<std::vector<size_t> > mpCoefficients;

	friend class boost::serialization::access;

	template<class Archive>
	void serialize(Archive & ar, const unsigned int version)
	{
		ar & mPrime ; ar & mKindependent ; ar & mpCoefficients ; ar & mWidth;
	}
}}}

All works in 64 bit mode.
