Sorry, I jumped to the conclusion to early. When called with -pedantic, 
g++ complains: 

/usr/local/include/boost/tuple/detail/tuple_basic.hpp: In function `typename
   boost::detail::tuples::make_tuple_mapper<T0, T1, boost::null_type,
   boost::null_type, boost::null_type, boost::null_type, boost::null_type,
   boost::null_type, boost::null_type, boost::null_type>::type
   boost::make_tuple(const T0&, const T1&) [with T0 =
   std::__normal_iterator<double*, std::vector<double, std::allocator<double> 
   >  >, T1 = double]':
[...] 
/usr/local/include/boost/tuple/detail/tuple_basic.hpp:564: invalid use of
   member
   `boost::detail::tuples::make_tuple_mapper<std::__normal_iterator<double*,
   std::vector<double, std::allocator<double> > >, double, boost::null_type,
   boost::null_type, boost::null_type, boost::null_type, boost::null_type,
   boost::null_type, boost::null_type, boost::null_type>::type'

It seems that pedantic g++ (v 3.0) requires even more ;O) typenames than
Comeau: 

template<class T0, class T1>
typename boost::detail::tuples::make_tuple_mapper<T0, T1>::type
inline make_tuple(const T0& t0, const T1& t1) {
  return 
     typename boost::detail::tuples::make_tuple_mapper<T0, T1>::type(t0, t1);
//   ^^^^^^^^^ 
}
