What feature?  Cygwin was designed with POSIX pathnames in mind.  If DOS
pathnames work, it is a fortunate side-effect, but not the primary
design goal, and not subject to stay the same in future releases.  The
only way to guarantee sane behavior from cygwin is to always use POSIX
pathnames.

DOS path - don't do that if you don't want surprises.  And if you want
bash to ignore \r, then reread the bash release announcements for
several ideas for doing this (including 'set -o igncr' or setting the
SHELLOPTS environment variable before bash is started).

If you are writing files for cygwin, then it is much preferred that you
omit CR, since cygwin emulates Linux which omits CR.  But if you must
interact with text mode files, then use a text mode mount or tell bash
that you plan on working with text mode and that bash should ignore CR.

/etc/fstab and set textmode mount points on the directories where you
want it.  But you _don't_ want it globally - for example it's great for
data files elsewhere in windows, but a bad idea for cygwin's /bin.
