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.
