In particular, FreeBSD 6 still uses the libarchive 1.x API and this correction will permit MFCing new libarchive features back to FreeBSD 6.

/*
|
|
* Background: There are two written standards for the tar file format.
|
|
* The first is the POSIX 1988 "ustar" format, the second is the 2001
|
|
* "pax extended" format that builds on the "ustar" format by adding
|
|
* support for generic additional attributes. Buried in the details
|
|
* is one frustrating incompatibility: The 1988 standard says that
|
|
* tar readers MUST ignore the size field on hardlink entries; the
|
|
* 2001 standard says that tar readers MUST obey the size field on
|
|
* hardlink entries. libarchive tries to navigate this particular
|
|
* minefield by using auto-detect logic to guess whether it should
|
|
* or should not obey the size field.
|
|
*
|
|
* This test tries to probe the boundaries of such handling; the test
|
|
* archives here were adapted from real archives created by real
|
|
* tar implementations that are (as of early 2008) apparently still
|
|
* in use.
