[boost] [filesystem] operations.hpp Won't Compile with VC10 using Boost 1.47

When I try to include boost/filesystem/operations.hpp, my code won't compile on MSVC 10 (Visual Studio 2010).  The error is from boost/filesystem/v3/config.hpp:49:

# if defined( BOOST_NO_STD_WSTRING )
#   error Configuration not supported: Boost.Filesystem V3 and later requires std::wstring support
# endif

I found only the following places where BOOST_NO_STD_WSTRING is defined, and none should apply, so I'm at a loss to understand why my build fails.  What have I missed?

./config/platform/amigaos.hpp:12:#define BOOST_NO_STD_WSTRING
./config/platform/symbian.hpp:85:#  define BOOST_NO_STD_WSTRING
./config/stdlib/libstdcpp3.hpp:23:#  define BOOST_NO_STD_WSTRING
./config/stdlib/modena.hpp:22:#define BOOST_NO_STD_WSTRING
./config/stdlib/sgi.hpp:100:#     define BOOST_NO_STD_WSTRING
./config/stdlib/stlport.hpp:109:#     define BOOST_NO_STD_WSTRING
