This shows that guess_category_value calls gl_locale_name_posix
directly, instead of calling gl_locale_name.  So the question now
becomes why does gettext do that, and whether it should do something
different at least on MS-Windows.

Also note that LC_MESSAGES is not supported by the Windows setlocale,
so either gettext should use some other category, or it will have to
invent stuff out of thin air, something I don't recommend.

Which in general sounds quite reasonable to me, btw, given the
description of your setup.

And what does setlocale(LC_ALL,NULL) return on that system?
