Did your static analyzer not notice that this dead code is
not even compiled?  I don't have a lot of faith in analyzers
that ignore #ifdefs.

(It's fair to ask why we haven't removed this code altogether
... laziness I guess, or waiting for something better than
GEQO to come along.  But expending effort on fixing it
is definitely not in the cards.)
