Localization with libstdc++ fails on FreeBSD

It looks like it has something to do with ctype, and nothing to do with
named locales.

Named locales only work on GNU systems, or with systems that implement
the new POSIX locale model (newlocale/duplocale/strcoll_l, etc). From
what I understand, neither FreeBSD 7 nor Darwin meet these requirements.
