encoding using Emacs 20 with additional private charsets defined will
probably not be read correctly by Emacs 21.
-** Not really a change (yet), but a projected one that of which you
-should be aware of: The variable `directory-sep-char' is deprecated,
-and should not be used. It was always ignored on GNU/Linux and Unix
-systems and on MS-DOS, but the MS-Windows port tried to support it by
-adapting the behavior of certain primitives to the value of this
-variable. It turned out that such support cannot be reliable, so it
-was decided to remove this variable in the near future. Lisp programs
-are well advised not to set it to anything but '/', because any
-different value will not have any effect when support for this
-variable is removed.
