Fix build error introduced in r5868.

Fix build error introduced in r5868.

aliased_name was a compatibility hack to match the output of the C rewrite
with the python version's results. It seems that we carried these
useless symbols with us for years, just without any impact good or bad.

By declaring devices static and tightening the screws (-Werror), the
compiler now knows that these declarations are useless - and stops.
