Don't rely on Cygwin advice on third-party sites; much of it is bogus.

This indicates that your cygwin1.dll is out of date (current: 2.2.1-1).
Stop all Cygwin processes, including services, then run Cygwin Setup
again and allow it to upgrade all packages.  If the 'cygwin' package is
not listed for upgrade, choose to reinstall it.
