I've uploaded an experimental version of tcsh, version 6.14.00-6.

This version is supposed to fix problems which are a result of the
textmode handling in the Cygwin version of tcsh.  Right now, up to
version 6.14.00-5, Cygwin's tcsh reads all input in textmode, thus
converting \r\n for all input from stdin, not only for commands and
script input.

This version 6.14.00-6 has been changed so that stdin is always read
in the mode with which the stdin file descriptor has been opened
originally, usually binmode, except for instance when redirected from
a file in a textmode mounted directory.

This should solve a couple of problems reported on the Cygwin list, for
example the problem with cvs and tcsh reported in
or stuff like the "protocol version mismatch" type of error, sometimes
reported by rsync if the remote shell is tcsh, as in

This version hopefully also fixes Cygwin's tcsh script misbehaviour.
Long scripts with DOS lineendings in a binmode mounted directory might
suffer from not being able to run longer for or while loops.  The
problem here is that long scripts are not kept fully in memory by tcsh.
So sometimes it has to seek within the script file.  For DOS files
written in textmode, tcsh then seeks to the wrong spot in the file.
However, I couldn't test this so far, so take this with a grain of salt.

To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page.  This downloads setup.exe to your
system.  Then, run setup and answer all of the questions.  Look for
"tcsh" in the 'Shells' category.  Because this is an experimental
version, you will have to use the 'Exp' radio button to access this
release of tcsh.
