commit dda82d1a7be51719013dd2c9d255a2e7790eed53
Author: Ken Brown <kbrown@cornell.edu>
Date:   Thu Oct 20 15:35:54 2016 -0400

    Add _PC_CASE_INSENSITIVE to [f]pathconf
    
    Update the getconf utility to support the new flag as well as
    _PC_POSIX_PERMISSIONS and _PC_POSIX_SECURITY.  These were previously
    unsupported, probably as an oversight.
