Why were the MICROSOFT parts removed?  The log message does not reveal
any reason, nor even tells about the removal.

Btw, is there any documentation on how to add support for character
maps not in the current CVS?  The only information I see is this
comment in the Makefile:

    #  If your system doesn't have the directory /usr/share/i18n/charmaps,
    #  get the source of the latest glibc, gzip all the charmap files in
    #  the directory "localedate/charmaps", and set the variable
    #  GLIBC_CHARMAPS to that directory.

This has two disadvantages:

  . You have no way of adding a charmap that is not in the glibc
    sources.

  . Downloading the humongous glibc distro just to get a small part of
    it is not my idea of fun.

Suppose I wanted to add codepage 853 support to Emacs: how would I go
about doing that?
