Hi Jon: I see new warnings with Debian stretch gcc:

tipc
    CC       misc.o
    CC       nametable.o
    CC       node.o
    CC       peer.o
misc.c: In function ‘hash2nodestr’:
misc.c:128:14: warning: pointer targets in passing argument 1 of
‘nodeid2str’ differ in signedness [-Wpointer-sign]
   nodeid2str(nr.node_id, str);
              ^~
misc.c:100:6: note: expected ‘uint8_t * {aka unsigned char *}’ but
argument is of type ‘char *’
 void nodeid2str(uint8_t *id, char *str)
      ^~~~~~~~~~
