Subject: (dump_file): Relativize link names before dumping.
X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;ds=sidebyside;h=eb5c8f4b8b84e341eec47833ccc9401b9293a0cf;p=chaz%2Ftar

(dump_file): Relativize link names before dumping.
This fixes a bug reported by Jose Pedro Oliveira.
(dump_file): Use offsetof when computing sizes for
struct hack; this avoids wasted space in some cases.
