Sounds like a problem w/ cygwin build of CVS. It could be circumventing
the I/O library calls which actually abide by the mount attributes,
though this seems like a surprising oversight.
It should probably accommodate both \r\n and \n deliberately in its code
if it's -kk.?, and simply ignore if -kb.

Thanks.  I remounted the directory in textmode.  But it still seems that
files I add to the repository get added with the CRLF line endings.

    [mlm CVSROOT]$ pwd
    [mlm CVSROOT]$ mount
    C:\cygwin\bin on /usr/bin type system (binmode)
    C:\cygwin\lib on /usr/lib type system (binmode)
    C:\cygwin on / type system (binmode)
    c: on /cygdrive/c type system (textmode)
    [mlm CVSROOT]$ cat > test
    a line with a CRLF ending
    [mlm CVSROOT]$ cat -A test
    a line with a CRLF ending^M$
    [mlm CVSROOT]$ cvs add -m "" test
    cvs server: scheduling file `test' for addition
    cvs server: use 'cvs commit' to add this file permanently
    [mlm CVSROOT]$ cvs ci -m "" test
    RCS file: /usr/local/mvroot/CVSROOT/test,v
    Checking in test;
    /usr/local/mvroot/CVSROOT/test,v  <--  test
    initial revision: 1.1
    cvs server: Rebuilding administrative file database

In the repository:

    address@hidden CVSROOT]$ cat -A test,v
    locks; strict;$
    address@hidden @;$
    date^I2001.;^Iauthor mlm;^Istate Exp;$
    @*** empty log message ***$
    @a line with a CRLF ending^M$

Similarly, if I check out a file that has LF line endings in the
repository, they are not translated into CRLF line endings on my

Any ideas?
