When using this type:

   boost::spirit::position_iterator<std::string::const_iterator>

I get a static assertion failure:

..\..\lib\boost_1_37_0\boost/iterator/iterator_adaptor.hpp(230) : error

         ]

This is triggered on a simple function declaration taking a 
position_iterator as argument, using MSVC8.0 Express on Windows XP.  It 
worked under Boost 1.36.0.
