Ok, now I have a little more useful information.  The file does have
"\r\n" line endings.  Even my original file, from the PC installation
which works.  So the Cygwin installed on the first PC (from a couple
of months ago) can deal with ^Ms, but the new install cannot.  I tried
creating an ordinary file with Emacs, and it also produces ^Ms (using
"vi -b" to verify).  I can't use this arrangement if the files
produced by Emacs are invalid with Cygwin.  Again, I don't have this
problem on the original installation.

So does this have something to do with one of the initial choices you
get when you run "setup", which is "Default Text File Type", choices
"Dos" or "Unix"?  In order to get this to work, do I have to
completely reinstall, selecting "Dos"?  I believe that when I
installed Cygwin on the first PC, I didn't get those choices.
