After a little bit more studying (combinatorical testing approach)
it seems that Johan's patch (or some patch of equivalent functionality)
is needed when:
the string and/or the pattern contain _fixed_ uppercase
If there is only lowercase data or the data has
alphabetical-thanks-to-locale data during runtime (as opposed to
compile-), the setlocale(LC_CTYPE, "") does seem to work.
