bug in dired-mark-sexp?

[Mathias Dahl]

I'm running GNU Emacs 21.3.50.1 on Windows XP and
dired-mark-sexp does not work. The error message I get is:

dired-mark-sexp: Search failed: 
"\\(Jan\\|Feb\\|Mar\\|Apr\\|May\\|Jun\\|Jul\\|Aug\\|Sep\\|Oct\\|Nov\\|Dec\\)"

I'm almost sure that this is because of how the dired
buffer looks like:

  z:/Docmaw/Core/Docmaw 2.2.0/Docmaw/Source/Java/ifs/Docmaw:
  total used in directory 2333 available 46509008
  drwxrwxrwx   1 mdahse   root            0 06-15 15:35 .
  drwxrwxrwx   1 mdahse   root            0 06-15 15:35 ..
  -rw-rw-rw-   1 mdahse   root        41713 2003-10-13

  -rw-rw-rw-   1 mdahse   root        34001 2002-12-26  
ApprovalCurrentStepOvw.java
  -rw-rw-rw-   1 mdahse   root         3630 2003-02-12  BookListLov.java

I have tested this using --no-init-file --no-site-file and
it still gives these kinds of dired lines.

When I test on my Mandrake box at home I get the names of
the months displayed in the dired buffer, and this of
course makes dired-mark-sexp much more happy.

Is this a bug or have I fscked up?
