I haven't looked yet. Can you describe what exactly the AC_TRY_RUN is
testing for?

If it's just whether the system supports strxfrm or UTF-8 at all that
might be ok. If it's detailed behaviour of the locales then that's a
problem since that could vary the platform the code is eventually run
on on compared to the one it's built on.
