It turns out this still isn't quite right.  Looks like we need:

#define NEEDS_GUARD_P(decl) (TREE_PUBLIC (decl) && (DECL_COMMON (decl) \
                                                    || DECL_ONE_ONLY (decl) \
                                                    || DECL_WEAK (decl) \
                                                    ||
(TARGET_WEAK_NOT_IN_ARCHIVE_TOC \
                                                       && DECL_LANG_SPECIFIC
(decl) \
                                                       &&
(DECL_EXPLICIT_INSTANTIATION (decl) \
                                                       || 
DECL_TEMPLATE_SPECIALIZATION (decl)))))

The former solution was dereferencing a null pointer.
