Is that the only unresolved reference? It is really weird that decrement() 
and other members aren't also unresolved. There is no difference in the way 
they are declared compared to increment().

The one thing that is a bit different compared to the path functions is 
that iterator is a nested class. Is it possible that BOOST_FILESYSTEM_DECL 
is required on the nested class declaration?

Could you please change path.hpp line 83 from:

    class iterator : public boost::iterator_facade<

to:

    class BOOST_FILESYSTEM_DECL iterator : public boost::iterator_facade<

and then let me know if that fixes the problem?

Thanks,
