Hello,
clang (c++11 support) fails on code like:

BOOST_STATIC_ASSERT((
             is_same< void, typename result_of< Fn() >::type >::value));

with error:

  no type named 'type' in 'boost::result_of<void (&())(X &)>'
             is_same< void, typename result_of< Fn() >::type >::value));
                            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~
../boost/static_assert.hpp:48:50: note: expanded from macro 'BOOST_STATIC_ASSERT'
#  define BOOST_STATIC_ASSERT( B ) static_assert(B, #B)
                                                  ^

Do you know why it fails? (other compilers like gcc, intel, msvc compile 
the code)

regards,
Oliver
