Hi.
I need to create tar archives with deep paths on a Linux machine that Solaris
10's system tar (ie /bin/tar) can extract. If I read the manuals correctly,
this should be achievable by using the USTAR format.

So the main difference seems to be that the file name is missing in the

Any suggestions for a patch?
Suggested patch against 1.15.91 attached.
