From 74aa54a1f6db109311e9bdc8cae64a2a26a2b860 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Mon, 29 Oct 2007 21:03:41 -0500 Subject: Make general list copy function Package dup needs to copy all members. Nathan had his implementation, but I generalized it to this new alpm_list function (and will use it in the next commit).
