fixes it, but then if decl has VISIBILITY_ANON, it should already be
!TREE_PUBLIC, so shouldn't that be if (!TREE_PUBLIC (decl))
constrain_visibility (guard, VISIBILITY_ANON, false); or even
if (!TREE_PUBLIC (decl) && DECL_INTERFACE_KNOWN (decl)) { DECL_INTERFACE_KNOWN
(guard) = 1; if (DECL_LANG_SPECIFIC (decl)) DECL_NOT_REALLY_EXTERN (decl) = 1;
}
?
