John

Here is what my mount command gives:
$ mount
C:\cygwin\bin on /usr/bin type system (textmode)
C:\cygwin\lib on /usr/lib type system (textmode)
C:\cygwin on / type system (textmode)

So I guess it is mounted in textmode. ;)

When installing cygwin I remember being asked if I wanted text-files
saved in "DOS or UNIX" mode. I guess this has to do with using different
line terminations. Since other people also may read my text files I
opted for "DOS" mode.

Regards,
Hallvard

I see the problem, but I don't know of a quick fix.

When you installed Cygwin, did you choose to mount the filesystems in
text mode?  If so, then I think you can mount the filesystems in binary
mode to avoid the bug.
