Thanks for your suggestion.  I believe my copy of textfile.txt has one
CRLF pair at the end, and the length is 76 bytes:

dpchrist@p42800e:~$ wc textfile.txt
 2 14 76 textfile.txt
dpchrist@p42800e:~$ wc textfile.out
 2 14 74 textfile.out


C:\cygwin\home\dpchrist>dir textfile.txt

C:\cygwin\home\dpchrist>type textfile.txt
This is a text file created with Notepad.
It has DOS (CRLF) line endings.

I do not understand the subtleties of Cygwin textmode mounts and binmode
mounts.  I do not recall taking any actions to affect this parameter --
my habit is to simply download Cygwin setup.exe, download packages to
the local disk, and install packages from the local disk.  When I
suspect my Cygwin installation is corrupt, I rename C:\cygwin, do a
fresh download/ download/ install cycle, and move over my data.  (Maybe
I need to do this again?)

Using ftp:://planetmirror.com, 5.2.1-4 appears to be the most recent
version of coreutils and it looks like I already have it installed (also
confirmed by the attached cygcheck.out).  The three previous mirrors on
the list also indicate 5.2.1-4 is current.  Is there a newer release?
Do I need to find a better mirror?

Reinstalling coreutils 5.2.1-4 anyway does not cure the problem:

dpchrist@p42800e:~$ grep dump .bashrc
alias dump='od -Ad -tc'
