A symlink, dangling or not, is a normal file. In any case, the problem is the same if the symlink target is a member in the archive. See for example % mkdir -p /tmp/mytest2; cd /tmp/mytest2 % tar xf cygwin-devel-3.5.0-0.295.g3bee68248fc8.tar.xz /bin/tar: usr/lib/libg.a: Cannot change mode to rwxr-xr-x: Not a directory /bin/tar: Exiting with failure status due to previous errors % I add that my symlinks are default ones, i.e. JUNCTIONS.
