From 927af790ee3ff1495acd2c6b33378a7ab20e0c67 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Sat, 12 Jan 2008 01:27:02 -0600 Subject: Convert deltas to dynamic allocation Another elimination of a static length structure in libalpm. Should result in a little more memory saved during execution of packages with lots of deltas attached.
