It throws whenever BOOST_POSIX is not defined.  It is just this (works
with 1.30.0, don't know about 1.31.0):

    void link( const path & from_file_ph,
               const path & to_file_ph )
      {
#   ifdef BOOST_POSIX
        if(::link(from_file_ph.native_file_string().c_str(),
                  to_file_ph.native_file_string().c_str()) != 0)
#   endif
        boost::throw_exception( filesystem_error(
          "boost::filesystem::symlink",
          from_file_ph, to_file_ph, fs::detail::system_error_code() ) );
      }
