According the hosts_access(3) man page the hosts_ctl() prototype should be in tcpd.h:

SYNOPSIS
     #include "tcpd.h" 

     extern int allow_severity;
     extern int deny_severity;

     struct request_info *request_init(request, key, value, ..., 0)
     struct request_info *request;

     struct request_info *request_set(request, key, value, ..., 0)
     struct request_info *request;

     int hosts_access(request)
     struct request_info *request;

     int hosts_ctl(daemon, client_name, client_addr, client_user)
     char *daemon;
     char *client_name;
     char *client_addr;
     char *client_user;

but it isn't:

$ cat h.c 
#include "tcpd.h" 

int main(void)
{
    hosts_ctl();
    return (0);
}
$ gcc -Wimplicit-function-declaration -c h.c 
h.c: In function ‘main’:
h.c:5:2: warning: implicit declaration of function ‘hosts_ctl’ [-Wimplicit-function-declaration]
$

The hosts_ctl() prototype should be added to the tcpd.h header file.
