You have to call to_string as to_string<char, std::char_traits<char>,
std::allocator<char>(). This is not a bug in this implementation, but a
feature of the language that found its way into bitset, which was
standardized before it was ever implemented.
V6.0 has trouble with function calls of the form f<type>(args), but V7.0
does not.
