BTW, I *do* see wieck < wiech in es_ES locale on HPUX 10.20, released
~1996. So I think we have correctly identified the core issue, and the
only interesting question is why mingw isn't following a more up-to-date
sorting rule.
Is it worth installing a variant rules regression output file for this?
I'd rather not, since that file tends to change often.
