The pdwtags program changed its whitespace formatting for enum values in release 1.19: @@ -145,22 +145,22 @@ u_int flags; }; enum admin_procedure { - ADMIN_PROC_CONNECT_OPEN = 1, - ADMIN_PROC_CONNECT_CLOSE = 2, - ADMIN_PROC_CONNECT_GET_LIB_VERSION = 3, - ADMIN_PROC_CONNECT_LIST_SERVERS = 4, - ADMIN_PROC_CONNECT_LOOKUP_SERVER = 5, + ADMIN_PROC_CONNECT_OPEN = 1, + ADMIN_PROC_CONNECT_CLOSE = 2, + ADMIN_PROC_CONNECT_GET_LIB_VERSION = 3, + ADMIN_PROC_CONNECT_LIST_SERVERS = 4, + ADMIN_PROC_CONNECT_LOOKUP_SERVER = 5, Workaround this by telling diff to ignore whitespace changes.
