This indicates to me that you're using binary mounts, am I correct?  It would
be normal for the \r to remain from the read when setting the variable with cat
if the file processing mode is set to binary.  If I'm correct, then you'll need
to filter the file to remove the \r just as you would on any UNIX environment
or you can move back to text mounts.

Also, which Cygwin dll are you using?  If it is stock b20.1 then see my pages
for more information.
