And then there is OpenSSH...

    joker@joker:~$ ssh localhost -D 127.0.0.1:0
    Bad dynamic forwarding specification '127.0.0.1:0'
    joker@joker:~$ ssh localhost -D 127.0.0.1:9999
    ssh: connect to host localhost port 22: Connection refused
    joker@joker:~$ ssh localhost -L 127.0.0.1:0:localhost:8080
    Bad local forwarding specification '127.0.0.1:0:localhost:8080'
    joker@joker:~$ ssh localhost -L 127.0.0.1:9999:localhost:8080
    ssh: connect to host localhost port 22: Connection refused
Oh well.
