Strange... I'm not familiar with STLport, but it looks as though your
compiler is reading <string> from STLport (hence the stlp_std::string)
but <ostream> from your compiler's STL (which doesn't know about the
STLport types.)  Or maybe it's parsing <ostream> before reading
<string>, and therefore doesn't know that std::string has been
associated in some way (#define? typedef?) to stlp_std::string.

My suggestion is to preprocess the source file being compiled (I don't
remember how to do it in Visual Studio---you might have to do it from
the command line) and see what string definition is in scope when
operator<< is defined. Let me know if you find out anything.

Later,
