looks like this.

it is a little bit strange, that in
/usr/include/d/dmd/core/sys/freebsd/config.d
there is ver 12:

```d
     version (FreeBSD_12) enum __FreeBSD_version = 1202000;
else version (FreeBSD_11) enum __FreeBSD_version = 1104000;
else version (FreeBSD_10) enum __FreeBSD_version = 1004000;
else version (FreeBSD_9)  enum __FreeBSD_version = 903000;
else version (FreeBSD_8)  enum __FreeBSD_version = 804000;
else static assert(false, "Unsupported version of FreeBSD");
```

but __FreeBSD_version is 1104000 anyway.
