At a first glance, I have two remarks:

The first is trivial: your #include guards are all symbols reserved to
the C++ implementation. No double underscores, please! They're also
not very unique. I use my initials and the date to help avoid

Instead of __JOIN__, I'd use something like JOIN_HPP_DWA20030128.

The second is nontrivial: I think you could probably simplify your
code a lot and increase portability at the same time by making better
use of Boost components, primarily MPL and iterator adaptors.
