It would be nice to verify this claim on as much systems as possible
Certainly POSIX has always required supporting -options, which is some
15 years old at least. Or do I mean 25? Either way ... And in
practice, every system I've ever used has a system tar supporting
-options, not just "old-style" options without the -.
Thus I would still propose that Automake always use -options to tar in
its output, never old-style options.
As for tar-v7, tar-ustar, tar-pax ... I don't know.
