// google: Those definitions are for codecvt<wchar_t>::id, codecvt<unsigned short>::id and codecvt<char>::id respectively.
// However, the codecvt<char16_t>::id and codecvt<char32_t>::id definitions aren't there, and indeed, if you look at locale0.cpp in the CRT source code you'll see they're not defined at all.
