    Refuse to run on Windows XP and earlier
    
    Refuse to run on Windows versions less than 6.0 (XP or previous), as they
    are no longer supported by Cygwin.
    
    Future work: The version checked against should be read from setup.ini,
    rather than hard-coded here, so that this version of setup cannot be used to
    download a future version of Cygwin which isn't compatible with the Windows
    version it's running on...
