(1)

It seems to me that 'nodosfilewarning' is "clean" and is "the Cygwin
ideal".  What is the problem using it?

(2)

Have people set the CYGWIN environmental variable?  I would think
that anyone who can handle the command line could handle that.

(3)

    Note to the CYGWIN DEVELOPERS:

        Now that the mount table is has moved from the
        Registry to a text file, perhaps it would make sense
        for cygwin1.dll to look at a text file, e.g.,
        /etc/cygwin.env, if the CYGWIN environmental variable
        is unset.

        This might also allow one to duplicate a cygwin
        installation by just copying a directory tree and the
        appropriate Windows batch files and shortcuts without
        having to run setup and without having set CYGWIN via
        the Control Panel | System | Advanced | Environmental
        Variables.

        Just a suggestion, not a request.  (I don't need it.)

(4)

Does the following work if you put it at the beginning of the batch
file?

set CYGWIN=3D%CYGWIN% nodosfilewarning

(Sorry I haven't tested - too much trouble.)

(5)

Tell people to always run from the current directory?

cd C:\
touch foo.txt

(6)

Don't use cygwin.

Compile the utilities of interest under MinGW.
	http://www.mingw.org/
(While you are there, look into MSYS and mingwPORTs.)

Find native utilities.  Here are the 2 I know about.
	http://sourceforge.net/projects/pw32/
	http://unxutils.sourceforge.net/
Note that they haven't been updated in a while.

(7)

Go back to 1.5.
