Testcase:

typedef long unsigned int size_t;
__extension__ typedef long int __time_t;
__extension__ typedef long int __suseconds_t;
typedef struct
{
}
__sigset_t;
struct timeval
{
  __time_t tv_sec;
  __suseconds_t tv_usec;
};
extern void bcopy (__const void *__src, void *__dest, size_t __n)
  __attribute__ ((__nothrow__)) __attribute__ ((__nonnull__ (1, 2)));
capture_next_packet (int bpf, int timeout, int *sz)
{
  struct timeval past, now, then;
    {
      bcopy (&then, &past, sizeof (then));
    }
}
