Hi,
after moving to a new position I have set up a fresh Cygwin installation:
CYGWIN_NT-5.1 sbhc123 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin
I use some Emacs extensions which execute external programs using
(call-process). This used to work on my previous setup, but it fails on
my current box. The following command run in Emacs reproduces what seems
to be the problem:
(call-process "bash" nil '(t t) nil "-ic" "ls -al")
bash: Kann die Prozessgruppe des Terminals nicht setzen (-1).:
Inappropriate ioctl for device
bash: Keine Job Steuerung in dieser Shell.
As you can see, my Cygwin also started speaking German, but I didn't get
round to fix that yet. The messages loosely translate to: "cannot set
terminal process group" and "no job control in this shell".
Is this an incorrect setup of either Cygwin or Emacs, or is this indeed
a problem that crept into Cygwin recently?
I can reproduce this problem. It reminds me of a problem that I reported in
http://cygwin.com/ml/cygwin/2011-06/msg00174.html ,
but that started with the 2011-05-05 snapshot and was fixed in the
2011-06-16 snapshot. The problem you're reporting exists in Cygwin
1.7.9 and persists in the latest snapshot, but with different symptoms:
Instead of printing error messages, emacs hangs and has to be killed.
If one of the Cygwin developers wants to look at this, here are the
steps to reproduce it:
1. Start emacs.
2. Type <Ctrl-x>b<Enter>
[This should put you in the *scratch* buffer.]
3. Type (or copy and paste) the following text into the *scratch* buffer:
(call-process "bash" nil '(t t) nil "-ic" "ls -al")
4. With the cursor positioned immediately after the closing parenthesis,
type <Ctrl-j>

P.S. The other problem you mentioned, that Cygwin started speaking
German, has already been reported and discussed at length. See
