That's a bug in Cygwin 1.7.0-28 where I screwed up user permissions.
Due to missing paranthesis in the code, the user has no rights to change
the permissions and DOS attributes on a file.  The missing execute
permissions don't really count anymore...

The fix requires two steps:

  - Update to Cygwin 1.7.0-29.
  - Either remove all files you created while using 1.7.0-28, or login
    with admin permissions and chmod all files with the desired permissions
    again.
