================================================================================
When I do some `Mx find-name-dired RET fmtcount-manual.tex RET on my PC
I get this *Find* buffer

--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
  c:/Nos_Programmes/MinGW/local/projects/fmtcount/:
  c:/Nos_Programmes/MinGW/msys/bin/find.exe . "(" -iname "fmtcount-manual.tex" ")" -ls

  889094   19 -rw-r--r--   1 Vincent  Administrateurs    36915 Jun  16:35 trunk/fmtcount-manual.tex

  find finished at Fri Jun 16 11:41:08
--8<----8<----8<----8<----8<--  end  -->8---->8---->8---->8---->8----

If now I try to visit one of the file by typing RET on its name, I get
the following error message:

--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
dired-get-file-for-visit: No file on this line
--8<----8<----8<----8<----8<--  end  -->8---->8---->8---->8---->8----

I guess that MSW MSYS find utility makes unusual output for the file
size or timestamp. This timestamp shows an hour:second

After doing some investigation it boiled down that function
dired-move-to-filename can't find the file name because of regexp in
directory-listing-before-filename-regexp. This regexp is equal to this:

"\\([0-9][BkKMGTPEZY]? \\(\\([0-9][0-9][0-9][0-9]-\\)?[01][0-9]-[0-3][0-9][ T][ 0-2][0-9][:.][0-5][0-9]\\(:[0-6][0-9]\\([.,][0-9]+\\)?\\( ?[-+][0-2][0-9][0-5][0-9]\\)?\\)?\\|[0-9][0-9][0-9][0-9]-[01][0-9]-[0-3][0-9]\\)\\|.*[0-9][BkKMGTPEZY]? \\(\\(\\([A-Za-z']\\|[^\x00-=]\\)\\([A-Za-z']\\|[^\x00-=]\\)+\\.? +[ 0-3][0-9]\\|[ 0-3][0-9]\\.? \\([A-Za-z']\\|[^\x00-=]\\)\\([A-Za-z']\\|[^\x00-=]\\)+\\.?\\) +\\([ 0-2][0-9][:.][0-5][0-9]\\|[0-9][0-9][0-9][0-9]\\)\\|\\([A-Za-z']\\|[^\x00-=]\\)\\([A-Za-z']\\|[^\x00-=]\\)+\\.? +[ 0-3][0-9], +[0-9][0-9][0-9][0-9]\\|\\([ 0-1]?[0-9]\\([A-Za-z]\\|[^\x00-=]\\)?

Looking a little more into it, I guess that Emacs is not the one to
blame. MSYS `find' utility outputs a strange time stamp where the month
and hour are displayed but not the day of month.

It is quite strange because on the one hand I get this:

--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
 $ ls -dils trunk/fmtcount-manual.tex
-| 889094 37 -rw-r--r-- 1 Vincent Administrateurs 36915 Jun 15 16:35 trunk/fmtcount-manual.tex
--8<----8<----8<----8<----8<--  end  -->8---->8---->8---->8---->8----

So `ls -dils' does the right job, but for some reason `find' outputs
something else:

--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
$ find . "(" -iname "fmtcount-manual.tex" ")" -ls
7281264   19 -rw-r--r--   1 Vincent  Administrateurs    36910 Jun  05:58 ./dist/fmtcount-manual.tex
889094   19 -rw-r--r--   1 Vincent  Administrateurs    36915 Jun  16:35 ./trunk/fmtcount-manual.tex
--8<----8<----8<----8<----8<--  end  -->8---->8---->8---->8---->8----

Maybe I could fix my configuration by configuring the command launched
by Emacs so that the `-ls' option is replaced by `-exec ls -dils {} +'

- Is that customizable at all ?
- Where to report bug to MSYS find ?

I checked the findutil version:

--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
 $ find --version
-| GNU find version 4.3.0
-| Features enabled: LEAF_OPTIMISATION FTS
--8<----8<----8<----8<----8<--  end  -->8---->8---->8---->8---->8----

This was not the latest one on sourceforge MSYS file tree, so I
installed the latest one (aka 4.4.2), but this does not solve the issue:

--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----

Why are you using MSYS programs with a native Windows build of Emacs?
Why not use a native port of GNU Find instead?

I don't think MSYS is actively maintained these days.

Please forget it, sorry for the distrubance.

I have customized my Emacs to get it around, and I have updated the
concerned bug report on MSYS tracker.

Just to be fully complete about this one, the silly reason was that:

1) MSYS/find was already installed on my machine.

2) MSYS/find was supposedly good enough because command find-name-dired
   only outputs relative paths.

3) I was not aware of MSYS/Find bug
   (https://sourceforge.net/p/mingw/bugs/2161/) --- or maybe I had
   forgotten about it, I have the impression that I had already met some
   similar issue quite some ago.


Now:

1) You are fully right, using EZWinPorts
  https://sourceforge.net/projects/ezwinports/files/findutils-4.2.30-5-w64-bin.zip/download
  does the job very well. In the end this is what I am doing now.

2) The other work around (which you may not like) is tampering the
   find-ls-option variable to set its car to "-exec ls -dils {} +" and
   continue with the MSYS find. I have tried that and it also fixes it,
   however I preferred to use EZWinPorts because the findutil is more
   recent and that allowed me to take the win64 port.

   Vincent.
