> As mentioned in this [post|http://markmail.org/message/36yuvstyykkgr3zo], the example program in section 34.2.3 -- Using Pointers or References to Streams of the User Guide is ill-formed:
> {quote}
>   at the very end of http://stdcxx.apache.org/doc/stdlibug/34-2.html
> there is an example of using a reference to create a "copy" of cout.
> However this example doesn't initialize the defined reference at once
> (which is required in C++) and for this reason doesn't compile with my
> gcc 4.2.1.
>   For convenience here is the example:
> {noformat}
> int main(int argc, char *argv[])
> {
>   std::ostream& fr;
>   if (argc > 1)
>     fr = *(new std::ofstream(argv[1]));
>   else
>     fr = std::cout;
>   fr << "Hello world!" << std::endl;
>   if (&fr!=&std::cout)
>     delete(&fr);
> }
> {noformat}
> {quote}
