4070	Incorrect header guard on fusion/include/has_keys.hpp	Joel Falcou	Joel de Guzman	"boost/fusion/include/has_keys has the following code:

#if !defined(FUSION_INCLUDE_HAS_KEY)
#define FUSION_INCLUDE_EMPTY

#include <boost/fusion/sequence/intrinsic/has_key.hpp>

#endif


the #define is obviously wrong and clash if empty.hpp is included afterward.

Fix is trivial."	Bugs	closed	Boost 1.43.0	fusion	Boost 1.42.0	Showstopper	fixed
