+	* OpenChange/MAPIStoreGCSMessage.m
+	(-getPidTagPredecessorChangeList:inMemCtx:): when the list is
+	missing, request a synchronisation from the container as the
+	message might now have been synchronised yet...

 	* OpenChange/MAPIStoreTypes.m (MAPICNCompare): new function that
 	returns an NSComparisonResult for two change numbers (reverse
 	format).
