Regardless of what happens on Windows, and I don't think it does that,
there isn't generally a language environment for all the relevant
coding systems.  I think processing locale specifications (and the
Windows equivalent) should be done differently, but no-one seemed to
agree when this last came up.  In particular, I was told it couldn't
work under Windows the same way as POSIX, for reasons I couldn't
follow.  (I haven't had a chance to implement something for Emacs 22.)

Note that windows-1251 & al aren't available until code-pages is
explicitly required, since coding system autoloading wasn't installed
and code-pages isn't preloaded.  It may interact with the codepage.el
nastiness.  (codepage has unfortunate special cases in various parts
of the Mule code and apparently can't be got rid of.)

I don't think there have been any significant changes for Emacs 21.3.
Cyrillic support is basically the same as it always was, since changes
were blocked.

Actually, I don't know what the correct definition for alternativnyj
should be -- I've never found anything that looked `official'.  I've
seen suggestions both that it's the same as cp866 and that it's not
the same.  I'd welcome an authoritative answer.

I can't check the original mail to see whether it's all accounted for
now, since the list isn't now being gated to gnusnet and I can no
longer access the GNU systems for the archive.  I don't know of any
missing features for Cyrillic, though.

[Users of Cyrillic who want improved support can look in
<URL:ftp://dlpx1.dl.ac.uk/fx/emacs/Mule>, which contains versions of
my original changes for use with Emacs 21.1.  There are coding
systems, language environments and input methods.  However, I think
there are some errors and omissions there which I haven't had time to
check.

Just to show it works, including in Gnus, here's
M-x list-charset-chars windows-1251:
