oddly enough, that doesn't include ja_JP; maybe the configure test that

Yes, it's indicating that test whether the ja_JP locale is supported is
incomplete. Can you run this program, please, and report the output?

Yikes! setlocale() is busted when handed an unrecognized locale, in that
it falls back to a completely different locale rather than failing!
