The setup.exe UNIX vs. DOS option only affects new installations. My
guess is that you have an existing text mount, which setup.exe won't
change; but to confirm that, you need to follow directions:

and include the output of 'cygcheck -svr' as a text attachment.

Again, bash only warns about \r errors on binary mounts if you have not
turned on the igncr option. Of course, the other alternative is to run
'd2u' (or the new 'flip') on your scripts so that they no longer have \r.
Don't work too hard, make some time for fun as well!
