My point is that the following will compile on most compilers:

template <class charT, class traits> class basic_ostream;

template <class charT, class traits, class Allocator>
class basic_ostringstream
        : public basic_ostream<charT, traits>
{
};

But you must fill out basic_ostream before you instantiate a 
basic_ostringstream.  Hopefully the job of filling out basic_ostream 
will be done for you when you #include <sstream>.  Otherwise you might 
have to #include <ostream> yourself.
