True 'nuff.

OK, now I see what's worrying you. Obviously, a local symbol in the
LINK_ONCE section can only be a problem if it is referred to by
something outside the LINK_ONCE section. The semantics of that are
really weird, anyhow, IMHO, although I am by no means a PE expert.
(I've actually researched PE to some degree, but by no means
exhaustively, in the past.)
