8346	Broken vc11 build at usage BOOST_STATIC_ASSERT_MSG after r82886	Vladimir Merzliakov <wanderer@…>	John Maddock	"After this commit my project code build fail with errors in boost headers at BOOST_STATIC_ASSERT_MSG uses.

What difference in then/else branches?

#  ifndef BOOST_NO_CXX11_VARIADIC_MACROS 
#     define BOOST_STATIC_ASSERT_MSG( ... ) static_assert(__VA_ARGS__) 
#  else 
#     define BOOST_STATIC_ASSERT_MSG( ... ) static_assert(__VA_ARGS__) 
#  endif 

Look like copy paste typo.
Change else to expected from old version code
#     define BOOST_STATIC_ASSERT_MSG( B, Msg ) BOOST_STATIC_ASSERT( B )
fix build problem.
