[boost] indirect_iterator

In trying to use the indirect_iterator on MSVC 6.5 I found that I cannot rely on indirect_iterator to automatically compute the value_type from the iterator_traits.  This despite the document saying: "In most cases the type of the elements being pointed to can be deduced using std::iterator_traits, but in some situations the user may want to override this type" although this gives no hint that any use of MSVC is one such "situation."  I don't think MSVC would have a problem with iterator traits except for true pointer types.  This is using boost 1.28.  So, my question is why is this necessary for non-pointer types that have well defined iterator_traits? and also, I thought I might suggest that it would be nice if the documentation covered this (for example, "in some situations, the user may want to override this type... On some compilers, the user may need to specify the value_type").
