Yes, but it should be possible to postpone the attribute's instantiation until there's a variable it can be applied to. ((aligned)) behaves that way, for example. I found a vague comment in the source (c-common.c, 5488), but it doesn't help much: /* ??? Could perhaps support cleanups on TREE_STATIC, much like we do for global destructors in C++. This requires infrastructure that we don't have generically at the moment. It's also not a feature we'd be missing too much, since we do have attribute constructor. */ Somewhat later is the following nice thought: /* ??? We could support pointers to functions here as well, if that was considered desirable. */ -- Leah
