iterator_adaptors on Tru64 version V6.1-027

Hi all,
I'm trying to use the iterator_adaptors class on Tru64. To make it
work I had to do the following changes:

In concept_check.hpp I had to change the code from this:

template <class Concept>
inline void function_requires()
{
#if !defined(NDEBUG)
  void (Concept::*x)() = BOOST_FPTR Concept::constraints;
  ignore_unused_variable_warning(x);
#endif
}

to this:

template <class Concept>
inline void function_requires(type<Concept> t = type<Concept>())
{
#if !defined(NDEBUG)
  void (Concept::*x)() = BOOST_FPTR Concept::constraints;
  ignore_unused_variable_warning(x);
#endif
}

because this compiler generates an error if a template parameter is 
not used in the function declaration. In iterator_adaptors.hpp I had 
to remove the parenthesis around all the if_true bool template 
parameter from this:

       typedef typename if_true<(  // original version
               ::boost::is_same<Value,typename 
iterator_traits<Iterator>::value_type>::value
           )>::template then<
                typename iterator_traits<Iterator>::pointer,
                Value*
       >::type pointer;
       
to this:

       typedef typename if_true< // Changed version no parenthesis
               ::boost::is_same<Value,typename 
iterator_traits<Iterator>::value_type>::value
           >::template then<
                typename iterator_traits<Iterator>::pointer,
                Value*
       >::type pointer;

It is possible to put this changes in the original distribution in 
order to avoid to put this changes in any new boost release I use ?

Thanks for your help
