Do you mean  I think 0.9.5 will leak a lot of memory on you,
but it should be OK if you haven't noticed that.

Actually in this case it looks like the fifo isn't used by
rdiff-backup, but is created just because a fifo is detected in the
source directory.  If you don't try to back up any fifos, rdiff-backup
will not mkfifo().  There is no --exclude-fifos option, but it
wouldn't be hard to add.  If you wanted to check to see if this is the
problem, try, for instance, applying this patch:

       = "Exclude device files"

Then when you use --exclude-device-files it will also exclude fifos.
Hopefully that will solve your "Function not implemented" error.

    However, I am more concerned with these messages:

  PE> Warning: Found unexpected
  PE> destination file
  PE> /cygdrive/e/
  PE> pt_mark.o, not processing it.  Warning: Found unexpected
  PE> destination file
  PE> /cygdrive/e/
  PE> pt_tcpmss.o, not processing it.  Warning: Found unexpected
  PE> destination file

These warnings are supposed to happen when a file is created while
rdiff-backup is running, but given the number of these messages that
probably isn't happening here.

    Just had a thought: is it possible that your destination file
system isn't case-sensitive?  Then things are bound to get screwed
up - suppose one directory on the source side has the files "File" and
"file".  Then they can't both be stored on the destination side.  Some
other poster reported that "unexpected .. file" message, but I didn't
think of the case sensitivity issue at the time.
