+From 42d01f060c5d764baa881d13c103d68897163a49 Mon Sep 17 00:00:00 2001
+From: Ryan Lortie <desrt@desrt.ca>
+Date: Mon, 12 Mar 2012 16:44:14 -0400
+Subject: gio-types.defs: change some enums to flags
+
+These flags types were originally incorrectly handled in glib as being
+enums.  That bug was fixed, but they're still enums here, leading to
+warnings about the mismatch.
+
+Change them to flags.
