I cant see why..

IMHO it does _not_ allow Linux behaviour:

----(Snipped from SUS)----
NAME

bind - bind a name to a socket

[...]

RETURN VALUE

Upon successful completion, bind() returns 0. Otherwise, -1 is returned and errno
is set to indicate the error.

ERRORS

The bind() function will fail if:

[...]

[EADDRNOTAVAIL]
The specified address is not available from the local machine.

-----------------------------
So binding to a non-local ip address shouldnt be allowed because it "is not
available from the local machine"; even if the machine has a dynamic ip.
