From 738be7a3ffec0a4053478d49821c7da9c5fd9ee6 Mon Sep 17 00:00:00 2001 From: Ethan Yonker Date: Wed, 10 Dec 2014 11:40:43 -0600 Subject: Use one mizip for all The new minzip did not compile in older trees due to needing mmap64. For older trees we will just use mmap instead. Remove all files and code pertaining to minzipold. Updater should now build properly in older trees as well. Eliminate use of PLATFORM_VERSION in favor of PLATFORM_SDK_VERSION which should be more consistent and reliable.
