 State-Changed-Why:
     This is the same issue as libstdc++/1704. I don't think this is a bug: please read the detailed commentary in 1704 and let me know what you think.
     
     There were some errors in your code: here's the corrected version. 
     
     Sorry it took me so long to get around to this.

     Here:
     
     truct outbuf: public std::streambuf
     {
       virtual int_type overflow (int_type c)
       {
         if (c != traits_type::eof())
           {
     	// does not work at all (characters are discarded).           
     	// c = std::toupper(c, getloc());
     	
     	// does work but does not convert.           
     #if 0	
     	std::use_facet<std::ctype<char> >(getloc()).toupper(c);
     	if (putchar(c) == EOF) 
     	  return traits_type::eof();
     #else
     	char cc = static_cast<char>(c);
     	cc = std::use_facet<std::ctype<char> >(getloc()).toupper(cc);
     	if (putchar(cc) == EOF) 
     	  return traits_type::eof();
     #endif
           }
         return c;
       }
     };
