Does the libstdc++ configure script show something like this?
Checking for C locale to use... darwin or freebsd

If not xlocale.h won't be used.

Even if it's used I'm not sure how well named locales work with the
darwin model, I think they fail even on Mac OS X for anything except
"C" and "POSIX", so maybe the same is true of FreeBSD. The closest
thing I have to a reference for that is Bug ID# 13969869 for
http://bugreport.apple.com but I can't see that report myself.
