+Subject: [PATCH] Use CUPS-1.6 IPP API getter/setter functions
+
+CUPS 1.6 makes various structures private and introduces these ippGet
+and ippSet functions for all of the fields in these structures.
+http://www.cups.org/str.php?L3928
+
+We define our own accessors when building against CUPS < 1.6.
+
+Based on work by Jiri Popelka <jpopelka@redhat.com> at
+https://bugzilla.gnome.org/show_bug.cgi?id=679759
