I think so, in the long run.  However, it should be done using the
POSIX 1003.1-2001 mechanism for extended headers.  The next version of
GNU tar is planned to use this mechanism, so it's probably better to
wait until after it is out before proceeding.

That depends on whether the set of calls is really a unit.  If some
non-Darwin systems (or different versions of Darwin) have some calls
and not others, then the configuration should use whatever calls are

No.  (That's not the Autoconf way.  :-)
