title: File permissions in cygwin and MVFS
body: <p>I am using Cygwin with a dll version of 1.5.19 (yes, out-of-date, I know, but we're doing it for configuration control reasons).  All my files (existing and newly created) show up with permissions 644, despite a umask of 022.  Also, using chmod doesn't change the permissions.  I have ntsec set in the CYGWIN environment variable.  I need to be able to add execute permissions; is there anything I can try to fix this or is it a lost cause?</p>
  
  <hr>
  
  <p>A much later note: I realized that a key part of the problem is that the files I was trying to chmod were in a ClearCase dynamic view, which uses MVFS.  I still have not found way to successfully set the execute permissions, though.</p>
