This firewall was not ported to RTEMS and is just dead code which may
make trouble during FreeBSD baseline updates. It also increased the
compile-time of the library for nothing.
Update #3472.
The following files are now provided by Newlib:
* arpa/inet.h
* net/if.h
* netinet/in.h
* netinet/tcp.h
* sys/socket.h
* sys/uio.h
* sys/un.h
The <sys/param.h> and <sys/cpuset.h> are now compatible enough to be
used directly.
Update #2833.
