Hi,

I'm trying to port a C++ application to Microsoft Windows using the 
Visual C++ environment (Express edition, if it matters) and I'm having 
some trouble with Boost.PropertyTree.

The following code works with GCC but fails to compile on Visual C++ 10.0:

#include <boost/property_tree/ptree.hpp>

int main()
{
   using boost::property_tree::ptree;
   ptree pt;
   return 0;
}

Here is a sample of the output:

[..]\boost\property_tree\detail\ptree_implementation.hpp(30):
error C2440: 'specialization': cannot convert from 'const std::string 
std::_Pair_base<_Ty1,_Ty2>::* ' to 'const 
std::basic_string<_Elem,_Traits,_Ax> std::pair<_Ty1,_Ty2>::* '
   with
   [
     _Ty1=const std::string,
     _Ty2=boost::property_tree::basic_ptree<std::string,std::string>
   ]
   and
   [
     _Elem=char,
     _Traits=std::char_traits<char>,
     _Ax=std::allocator<char>,
     _Ty1=const std::string,
     _Ty2=boost::property_tree::basic_ptree<std::string,std::string>
   ]

Can someone reproduce the bug? If so, is there some kind of workaround, 
even if it requires hacking the library?

Thank you,
