Complex Numbers

We are already aware of this issue, since you have already reported
it ;) The relevant PR is middle-end/18902.

Indeed, our plan involves enabling the (*already available*) algorithm
due to Smith. There are still some open issues, however (see "Depends on"
and "blocks" fields, for further details).

As usual, patches are *welcome*, if prepared according to our (usual)
rules and the necessary copyright assignment is in place.

Paolo.
