But your client isn't windows.  It's cygwin.

Right.  You're not on windows.

Yep.  Native windows builds explicitly open the destination files in
textmode.

Not surprising that this did not make a difference.  It's a client side
thing, not
a server-side thing.

Nope, it's a client file-IO thing, not a console-IO thing.

This is the "problem".  If you want the files on your hard drive to be
text (DOS) mode, then you need to checkout onto a drive that is mounted
in textmode.  HOWEVER: the native windows build of cvs has many hooks in
it to deal with the CR/LF translation issue (e.g. so that cvs diff
output is okay, and cvs update doesn't go haywire).  The cygwin build of
cvs just relies on the kernel's (cygwin1.dll) support of dos/unix mode
mounting.  I do NOT KNOW if that is sufficient to make 'cvs diff' and
'cvs update' act correctly in these circumstances.

Try it somewhere non-critical (and report back to the list)
