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.
