Thanks. We need this to build on 32bit systems:

--- a/tidbits/oob-net-ping.c
+++ b/tidbits/oob-net-ping.c
@@ -215,7 +215,7 @@ static size_t build_icmp_request(uint8_t *o_frame, size_t icmplen,
 	icmphdr->checksum = cksum;
 
 	if (verbosity > 1) {
-		evl_printf("ip_len=%zd, icmp_len=%zd, ip_len=%d, datalen=%ld\n",
+		evl_printf("ip_len=%zd, icmp_len=%zd, ip_len=%d, datalen=%zu\n",
 			   sizeof(*iphdr), sizeof(struct icmphdr),
 			   ntohs(iphdr->ip_len), datalen);
 		print_ip_header(iphdr);

What about turning this code into the (currently missing) 'evl-ping'
utility? I believe it is of general interest to any user.
