My plain tar command under solaris cannot handle the pax files, too.
So ustar archives should be created (at least under solaris).

But I don't know why the ustar format can handle long file names,
whereas the gnu format creates a "@LongLink" file and pax a "PaxHeader"
file (when unpacked with tar).
