That does indeed makes a difference:

--8<---------------cut here---------------start------------->8---
$ emacsclient -e "(message \"hello\")"

*ERROR*: End of file during parsing
--8<---------------cut here---------------end--------------->8---

--8<---------------cut here---------------start------------->8---
$ /usr/bin/emacsclient -e "(message \"hello\")"
/usr/bin/emacsclient: can't find socket; have you started the server?
To start the server in Emacs, type "M-x server-start".
--8<---------------cut here---------------end--------------->8---

However, that still leaves me with the following problem:

  How can I work in a correct shell on Windows (read: not `cmd.exe'), and
  edit in my graphical Emacs w32?

More generally, as:

- it happens I switch between GNU Emacs 23/24 versions (for test purpose, in
  case of problem)

- an Emacs server must be contacted by an `emacsclient' of the same release

- Cygwin (/usr/bin) is second in my PATH, after ~/bin

I currently have a small `~/bin/emacsclient' script (one-liner) which allows me
to set the full path to the right `emacsclient' without having to fiddle with
the PATH environment variable (as that requires me to quit my shell, and start
a new one):

--8<---------------cut here---------------start------------->8---
"C:/Program Files (x86)/emacs-trunk/bin/emacsclient" $@
--8<---------------cut here---------------end--------------->8---

This is a hack. Indeed, I'd like to be able to launch whichever Emacs version
(clicking on one of the many versions I have on my Windows desktop), and that
launching `emacsclient' in the shell would work in all contexts.

Am I missing a better way to handle this?

Best regards,
