Used a small test program (thanks Alexander)

#include <libzoneinfo.h>
#include <locale.h>
#include <stdio.h>

int main()
{
  char *cur_country = NULL;
  int nctnt, i;
  struct  tz_continent *ctnts = NULL;
  struct tz_continent *pctnt = NULL;
  char *cntry_name;
  int nctry;
  struct tz_country *cntries;
  struct tz_country *pctry;



  setlocale(LC_MESSAGES, "");
  nctnt = get_tz_continents(&ctnts);

  if (nctnt == -1) {
       printf("No continent data\n");
  }


  for (i = 1, pctnt = ctnts; pctnt != NULL;
          pctnt = pctnt->ctnt_next, i++) {

          nctry = get_tz_countries(&cntries, pctnt);
          printf("%s  - %d\n", pctnt->ctnt_name, nctry);
  }

  return 0;
}
