If you're going to use @code, you should use ".bss" instead of "bss".
If you use dfn, use BSS instead of bss.  Use BSS (undecorated - it's
just an acronym) when referring generically to the uninitialized data,
and @code{.bss} when specifically talking about the COFF section by
that name.  Yeah, sometimes it will be hard to decide, but they're
fairly interchangeable.

No, the stub zeros out bss at run-time.  If you're running an unexec'd
image, the unexec should change the .bss memory range to .data so that
it acts like initialized data.
