21 # Problem: If a member with link count > 2 was stored in the archive twice,
22 # previous versions of tar were not able to extract it, since they
23 # were trying to link the file to itself, which always failed and
24 # lead to removing the already extracted copy. This script tests
25 # the workaround by Paul Eggert that leaves the extracted copy
