To add to this old thread: OpenSSH has now also decided to drop tcpwrap.

Some of the posts in this thread are actually quite entertaining.

For example, the first call of hosts_access() is setjmp(), which is just
beautiful... We probably should make setjmp()-freeness a requirement for
all code included in Fedora.
