/* The target member is reused for adding new actions, the

|
* For backward compatibility, the 4 lsb (2 would be enough,
|
|
* but let's play it safe) are kept to designate this target.
|
|
* The remaining bits designate the action. By making the set

|
* action 0xfffffff0, the result will look ok for older

* versions. [September 2006] */
