where are char_traits<wchar_t> instances built ?

[Marc Espie]

I'm making progress on getting an i386 OpenBSD system running with
gcc 3.3.2.

So far, the basic system is running, XFree4 as well, and ports are churning
along.

I've run into a small issue: id3lib protests that it can't find:
std::char_traits<wchar_t>::compare(wchar_t const*, wchar_t const*, unsigned)

and similar functions.

So, where are those functions instantiated ?

Looking in my libstdc++, I see no instance of
std::char_traits<T>::compare, either for T=char nor T=wchar.

There's probably some configure misfiring, but I could use a little help
figuring it out quicker...
