Problem in dired-mode

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.7.1 (rs6000-ibm-aix4.3.3.0, X toolkit)
 of Fri Sep 15 2000 on zam253
configured using `configure  --prefix=/usr/local/emacs20 --with-x11 
--with-gcc=no --with-x-toolkit=athena'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

First: this error only occurs on AIX-machines...on others like Linux
       IRIX(SGI), COMPAQ(OSF) and Solaris the new emacs works fine.
description:
        Starting emacs entering the directory mode, there are two types of
        dates: time stamp (eg: 15:03) and years (eg: 1999).
        files with the time-stamp entry works fine, but that with the year
        are not be able to opend by pressing 'e' or by clicking the 
        middle mouse button. 
        may be, there is an entry like
             -rw-------   1 zdv124   zam         7943 Jan 03 2000  Kalender99
        (so we have a file >Kalender99<) and I try to open it by pressing 'e', 
        I get the error message:
             "File no longer exists; type `g' to update Dired buffer" 
        If I would make a command on it (by selecting it and pressing 
<SHIFT>+<1>) 
        like 'touch', I get this result: (after pressing 'g')
             -rw-------   1 zdv124   zam         7943 Sep 15 14:07  Kalender99
             -rw-------   1 zdv124   zam         7943 Jan 03 2000  Kalender99
        There is a new file > Kalender99<. 
        The filename-string has a leading blank!
        I tried to correct this, and I located it in
File: /usr/local/emacs20/share/emacs/20.7/lisp/dired.el
...
(defvar dired-move-to-filename-regexp
...
        ;; weiand: changed: year potentially unaligned
        ;; St.Graf, Research Centre Julich, 15.9.00 (my comment)
        ;; old, but correct (my comment)
        s "\\(" HH:MM "\\|" s yyyy "\\|" yyyy s "\\)"))
        ;; new, but wrong         s "\\(" HH:MM "\\|" s "?" yyyy "\\|" yyyy s 
"\\)")) (my comment)
...
<EOF>


Now, the new emacs works fine.
