--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
get_guard used to do:
-      if (TREE_PUBLIC (decl))
-       DECL_WEAK (guard) = DECL_WEAK (decl);
and doesn't anymore, so either it should be readded this way, or perhaps
instead look for weak attribute on decl if TREE_PUBLIC and set DECL_WEAK in
that case?
