Thank you for the info but we seem to have nothing to do.  For
the interactive use, Reiner has already changed `mm-codepage-setup'
so as to signal an error as:

`codepage-setup' is obsolete in this Emacs version

For the non-interactive use, i.e. the usage in `mm-charset-eval-alist',
`mm-charset-to-coding-system' that exclusively uses it will never call
`codepage-setup' since the charsets listed in `mm-charset-eval-alist'
by default don't need to be aliases.  Even if a user modifies the value
of `mm-charset-eval-alist' strangely, `mm-charset-to-coding-system'
will silently end up as follows:

(condition-case err
    (let ((mm-charset-eval-alist
           '((windoze-9999 . (mm-codepage-setup 9999 t)))))
      (mm-charset-to-coding-system 'windoze-9999))
  (error err))
 => nil

For a person who uses `mm-codepage-setup' in a custom function,
he will realize that it cannot be used soon.
