Hi folks,

After I did a git pull, I started getting this error:

  CC       packet-lorawan.lo
packet-lorawan.c: In function 'dissect_lorawan':
packet-lorawan.c:657:7: error: variable 'frame_length' set but not
used [-Werror=unused-but-set-variable]
  gint frame_length;

Seems to be related to this:

        frame_length = current_offset;
+#if GCRYPT_VERSION_NUMBER >= 0x010600 /* 1.6.0 */
        if (encryption_keys) {
                guint8 *msg = (guint8
*)wmem_alloc0(wmem_packet_scope(), frame_length + 16);
                msg[0] = 0x49;

                }
-       } else {
+       } else
+#endif
+       {

It's a bit rude to cause build errors just because I don't have gcrypt
1.6.0 or above.
