Thanks for the support. Even BOOST_STATIC_ASSERT isn't working.

#include <boost/static_assert.hpp>
#include <boost/fusion/sequence.hpp>

int _tmain(int argc, _TCHAR* argv[])
{
   typedef boost::fusion::map< boost::fusion::pair<int, char>
                             , boost::fusion::pair<char, char>
                             , boost::fusion::pair<double, char>
                             > mymap;

   BOOST_STATIC_ASSERT(( boost::is_same< char, char >));

        return 0;
}

The error are now:
