I didn't check it again, but IIRC there have been some changes in
that area:

- Warnings about variables which are accessed only by
initializing or finalizing have been changed. (Additional
compiler options?)

- Variables may be called unused, even if only their contents is
potentially unused. (potentially overwriting the contents of an
in out parameter before using the contents)

(But I don't have the list of changes within reach.)
