fortran-blink-matching-do fails

In GNU Emacs 21.2.1 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2002-04-09 on tfkp12
configured using `configure  --prefix=/nfs/common --libexecdir=/nfs/common/lib 
--mandir=/nfs/common/share/man --infodir=/nfs/common/share/info --with-gcc 
--with-pop --with-x --with-x-toolkit=athena i386-pc-linux'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: POSIX
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil

  default-enable-multibyte-characters: nil

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

In emacs 21.2 the regexp in fortran-beginning-do for finding the
matching `DO' has been modified such that now it is matching DO
statements with a statement number. -- But `END DO' statements refer
to `DO' statements without a statement number so that now
fortran-blink-matching-do fails. Could you please go back to the
correct behavior of emacs 21.1?

Or am I missing here anything?

Thanks a lot,
