Hi,
I applied the below patch as obvious. Some languages didn't fit
into the original ISO 639 two character language code, so the standard
has been extended to allow three character codes as well. These are
used, for instamce, on Linux and Windows for a couple of languages.
The below patch just adds two lines to loadlocale() which allow to
specify three character language codes as well.
Of course this is still just fake, but I'm working on extending the
loadlocale() function for Cygwin to allow only languages and territories
which are actually supported on Windows, and subsequently fetch
LC_COLLATE, LC_MONETARY, LC_NUMERIC, and LC_TIME information from
Windows.
