in my dev-c++ 4.9.7.0 + gcc 3.2 it's already uncommented but somebody
forget
to recompile the library with it :-(

you probably wanted to write:
fish = (wchar_t * ) "fish";
weren't you?
but it still want be correct as the correct syntax is
fish = L"fish";
and it should be written to wcout instead of cout

p.s.
it's better to
#include <iostream>
using namespace std;
instead of
#include <iostream.h>
and btw C++ standard knows only main returning int (not void)

Thanks in advance,
