GCC problem

I switched my code over to using what I believe to be the K&R style
function definitions.

63 /*pcap_loop callback routine*/
64 void
65 capture_callback(buffer, packet_header, data)
66 u_char *buffer, const struct pcap_pkthdr
*packet_header, u_char *data;
67 {
68 total_captured_packets++;
69 if (display == true)
70 {
71 fprintf(stdout, "Received packet %d\n");
72 }
73 if (cache_packets == true)
74 {
75 struct packetCache *pc;
76 if ((pc = malloc(sizeof *pc + packet_header->len)) ==
NULL)
77 {
78 fprintf(stderr, "Memory Allocation Error!\n");
79 fprintf(stderr, "Turning off caching\n");
80 cache_packets = false;
