Recently I tried to compile tcpdstat tool, which is a part of tcpd-tools-0.9. It didn't compile, giving such errors:
$ make cc -g -Wall -I. -DINET6 -c stat.c stat.c: In function 'main': stat.c:123: warning: implicit declaration of function 'strcmp' stat.c: In function 'show_stat': stat.c:264: warning: implicit declaration of function 'localtime' stat.c:264: warning: assignment makes pointer from integer without a cast stat.c:265: error: dereferencing pointer to incomplete type stat.c:265: error: dereferencing pointer to incomplete type stat.c:266: error: dereferencing pointer to incomplete type stat.c:266: error: dereferencing pointer to incomplete type stat.c:266: error: dereferencing pointer to incomplete type stat.c:267: warning: implicit declaration of function 'ctime' stat.c:267: warning: format '%s' expects type 'char *', but argument 2 has type 'int' stat.c:269: warning: format '%s' expects type 'char *', but argument 2 has type 'int' make: *** [stat.o] Error 1
And such ones:
$ make cc -g -Wall -I. -DINET6 -c net_read.c net_read.c:140: error: static declaration of 'packet_length' follows non-static declaration tcpdstat.h:74: error: previous declaration of 'packet_length' was here net_read.c: In function 'ether_encap_read': net_read.c:316: error: 'ETHERTYPE_IPV6' undeclared (first use in this function) net_read.c:316: error: (Each undeclared identifier is reported only once net_read.c:316: error: for each function it appears in.) net_read.c: In function 'atm_if_read': net_read.c:435: error: 'ETHERTYPE_IPV6' undeclared (first use in this function) net_read.c: In function 'ip_read': net_read.c:553: error: 'struct tcphdr' has no member named 'th_sport' net_read.c:554: error: 'struct tcphdr' has no member named 'th_dport' net_read.c:562: error: 'struct udphdr' has no member named 'uh_sport' net_read.c:563: error: 'struct udphdr' has no member named 'uh_dport' net_read.c: In function 'ip6_read': net_read.c:650: error: 'struct tcphdr' has no member named 'th_sport' net_read.c:651: error: 'struct tcphdr' has no member named 'th_dport' net_read.c:659: error: 'struct udphdr' has no member named 'uh_sport' net_read.c:660: error: 'struct udphdr' has no member named 'uh_dport' net_read.c: In function 'ip4f_cache': net_read.c:875: error: 'struct udphdr' has no member named 'uh_sport' net_read.c:875: error: 'struct udphdr' has no member named 'uh_sport' net_read.c:876: error: 'struct udphdr' has no member named 'uh_dport' net_read.c:876: error: 'struct udphdr' has no member named 'uh_dport' net_read.c: In function 'ip4f_lookup': net_read.c:885: warning: implicit declaration of function 'TAILQ_FIRST' net_read.c:885: warning: assignment makes pointer from integer without a cast net_read.c:886: warning: implicit declaration of function 'TAILQ_NEXT' net_read.c:886: error: 'ip4f_chain' undeclared (first use in this function) net_read.c:886: warning: assignment makes pointer from integer without a cast make: *** [net_read.o] Error 1
etc. So I did such changes to sources:

Seems it works. The code compiles and seems to somehow work. Hope it will be useful to somebody.
