Please don't try to use it :-) Yeah that's a funny hack. I don't think it's required though, but I'm just running through some more tests. I think I found an improvement with the thin archives as well -- we were still building symbol table after removing the s option (that only avoids index). "S" is required to not build symbol table. I'll send out an RFC on a slightly more polished patch series shortly. Thanks, Nick
