Re: [PATCH 0/1] MR1015: wpcap: use UNIX 98/BSD 4.4 sockaddr header

We should check BSD variants instead, like this:

```
#if defined(__FreeBSD__) || defined(__FreeBSD_kernel__) || defined(__NetBSD__) || defined(__OpenBSD__) || defined(__DragonFly__) || defined(__APPLE__)
```

Another option would be to check the existence of `sa_len` in `struct sockaddr` via autoconf, but glibc doesn't seem to do that.
