Hi,

I have just run into a Cygwin vs Linux oddity that I cannot explain. I've
managed to trace the problem back to a very simple statement:
  echo "$(echo -e '\r')" | od -x
on my W2K Cygwin install (Cygwin1.dll 2005/04/01), this produces
  0000000 000a
  0000001
On Linux, this command produces:
  # echo "$(echo -e '\r')" | od -x
  0000000 0a0d
  0000002
(which is what I'd expect). 
Also, the Cygwin command
  echo -e '\r' | od -x
also returns
  0000000 0a0d
  0000002
which is , again, what I would expect. I've tried setting CYGWIN to 'tty
binmode' but it did not make a difference. 

What am I doing wrong here?

thanks in advance,

JJ Keijser
