I have just checked, following code works OK:

template<typename T>
inline typename boost::enable_if_c<boost::mpl::not_< boost::is_float<T> 
 >::value, int>::type
foo( T&& v );

template<typename T>
inline typename boost::enable_if_c<boost::mpl::not_< boost::is_float<T> 
 >::value, int>::type
foo( T&& v )
{
     return 1;
}
