Milestone:  To Be Determined   |   Component:  None      
  Version:  Boost 1.46.1       |    Severity:  Problem   
 Keywords:  append relative    |  
-------------------------------+--------------------------------------------
 Currently the following is a no go:

 boost::filesystem::path a("foo/bar"), b("test/korv");
 a.append( b.begin() + 1, b.end() ); // Expects a == "foo/bar/korv"

 This is because append() is strictly for iterators of string types it
 would seem. I suggest adding the following specialization ( or something
 along these lines ):

         template < >
         path& path::append< path::iterator >( path::iterator begin,
 path::iterator end, const codecvt_type& cvt)
         {
                 for( ; begin != end ; ++begin )
                         *this /= *begin;
                 return *this;
         }

 I've attached an example of make_relative which uses this functionality.
