Well, the first thing that comes to mind is that strxfrm() is
returning strings that, when sorted, do not give the same order we
would have obtained via strcoll(). It's true that there are existing
callers of strxfrm(), but it looks like that is mostly used for
statistics-gathering, so it's possible that differences vs. strcoll()
would not have shown up before now. Is there any legitimate way that
strxfrm() and strcoll() can return inconsistent answers - e.g. they
are somehow allowed to derive their notion of the relevant locale
differently - or is this just a case of Cygwin being busted?
