bug#3428: 23.0.94; Missing source files?

In GNU Emacs 23.0.94:

There are several files in emacs-23.0.94/lisp/international
that are automatically generated from files that aren't in the Emacs
distribution. Is that an oversight? At least

  charprop.el, eucjp-ms.el, uni-name.el and uni-old-name.el

have comments about being automatically generated from such files.
The files I'm missing are 

  unidata-gen.el, eucJP-13th.txt, eucJP-udc.txt, eucJP-ibmext.txt
  and UnicodeData.txt

judging by those comments.
