I think this is likely to result in a lot of complaints about rightmost_one_pos[] being unreferenced, in non-HAVE__BUILTIN_CTZ builds. Probably that has to be an extern rather than static in the header. leftmost_one_pos[] likewise. I might have a go at improving the configure tests later --- I still don't like that they're compile-time-optimizable. But that can wait. regards, tom lane
