I added a new function, rw_fnmatch(), to the test driver. It behaves

like the POSIX fnmatch() (the FNM_XXX constants aren't implemented

STDCXX-683 it should make it easier to also implement a scheme like
the one outlined below.
Travis, feel free to experiment/prototype a solution :)

What expression should be used to get an appropriate set of locales for a
given platform? I can't really expect a filter for all UTF-8 locales to
work
on all platforms as some don't have those encodings available at all. If
I
filter by language, then I may be limiting the testing to some always
correct subset. Is that acceptable for the MT tests?
I think the MT ctype tests just need to exercise a representative
sample of multi-byte encodings (i.e., MB_CUR_MAX between 1 and
MB_LEN_MAX). There already is some code in the test suite to find
locales that use these encodings, although it could be made more
efficient. I don't know how useful rw_fnmatch() will turn out to
be in finding these codesets since their names don't matter.

Actually, I think I meant to say single threaded tests. Those are the ones
that currently test every locale. The multi-threadede tests already test a
subset of locales, though the method for selecting those locales may vary
between tests.
I don't think it is right to test a fixed set of locales based on language,
country, or encoding. If you agree, then we probably agree that the proposed
enhancement doesn't actually do anything useful [and I've wasted a bunch of
time]. If this is the case, then we need to propose another solution for
selecting locales.
I think testing a small subset of installed locales should be enough.
In fact, for white box testing of the ctype facets, exercising three
locales, "C" and two named ones, should be sufficient.
If I am wrong, and it is useful for testing [and more specifically how it
would be useful for fixing STDCXX-608], then I'd like to hear how.
What do you propose?
