If suggestions others have made already don't help, I'd recommend falling
back to <http://cygwin.com/problems.html> if you need more help from this
list. Right now, I'm not really sure what file-system you're working with
and the tools in use. The 'cygcheck' output that the link above recommends
*attaching* to problem reports will help clarify some of these questions.
I'd also like to see the output of 'type -a cat vi chmod'. In addition, it
would be helpful to know what directory you are in.
