Legally? If the source code was posted by the author to the wiki, it can remain on the wiki under whatever licence (GFDL or CC-BY-SA) was in use at the time it was posted.

If you want to move the code elsewhere, then the original license and attribution must be retained. That may mean we have (if not otherwise indicated) bits of programme code under what was intended to be a documentation license - but that's not the same as unlicensed code.
