Unlike a few other recent messages with "clisp" in the
subject, this one is actually about CLISP!
I'm using version 2.36 as downloaded from a Cygwin mirror,
and my *default-file-encoding* uses dos-style line
terminators
[1]> *default-file-encoding*
#<ENCODING CHARSET:ASCII :DOS>
even though my Cygwin installation is set to use unix ones.
I poked around in the source, but couldn't figure out when
or how CLISP decides what to set this to. How do I get it
to use :UNIX?
Thanks,

(In clisp-2.41) it's in encoding.d, line 2535: (encoding_from_name and
init_dependent_encodings). If you don't specify a -E or -Efile
option, it'll be taken from the locale, and it selects the
line-terminator so:
#if defined(WIN32) || (defined(UNIX) && (O_BINARY != 0))
pushSTACK(S(Kdos)); /* :line-terminator */
#else
pushSTACK(S(Kunix)); /* :line-terminator */
#endif
So it seems that Cygwin is not considered a UNIX at compilation
time...
On the other hand, it appears we cannot specify a line terminator from
the command line, so there remains two ways to handle the situation:
Start with:
clisp -x '(setf custom:default-file-encoding (ext:make-encoding :charset charset:iso-8859-1 :line-terminator :unix))' ...
or put:
(setf custom:default-file-encoding (ext:make-encoding :charset charset:iso-8859-1
:line-terminator :unix))
in '~/.clisprc'.
You can do that with:
clisp -x '
(with-open-file (out (make-pathname :name ".clisprc" :type nil :version nil
:defaults (user-homedir-pathname))
:external-format (ext:make-encoding :charset charset:iso-8859-1
:line-terminator :unix)
:direction :output
:if-does-not-exist :create
:if-exists :append)
(pprint '(setf custom:default-file-encoding
(ext:make-encoding :charset charset:iso-8859-1
:line-terminator :unix)) out))
'

Just a tiny mistake that I stumbled over when I tried this: the symbol
is called `custom:*default-file-encoding*', not
`custom:default-file-encoding'.

Of course. Sorry for the confusion.

Aha!
Before my original post, I tried setting *default-file-encoding*
from .clisprc as you described. This works for files opened
by me, but not for standard output (presumably because its
line terminator is set before .clisprc or similar code is
run -- there's no way to update an already-open stream's
:external-format, is there?).
I'm going to
1. Hand-hack the above lines to force the use of Kunix, and
recompile.
2. Find out what needs to be done to CLISP's Cygwin version
so that it uses the line terminator that Cygwin has been
configured to use.
Thanks to both you and Wolfram for your help.

This is something that clisp should not do in order to be considered a
cygwin package.
It should take the terminator it uses from cygwin, in which it is a
setup option.
It is probably best to report it as a bug to both the developers of
clisp and the cygwin packager of it. (Even though it can be fixed).

For the benefit of anyone who has this problem and finds
this thread in a search, the problem is fixed in version
2.41-2:

Thanks to denizens of comp.lang.lisp and the Cygwin list for
their help and to Reini Urban for doing the fix.
