From bce140ebb905617295eff5f2b79152d42d217b32 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Tue, 3 Jan 2017 17:51:04 +0100 Subject: musl: update musl to 1.1.16+ and switch to download from git This patch updates musl to 1.1.16+ [0] and removes all the backported patches. This is a major release and tagged as such. For more information visit musl-libc.org or read the WHATSNEW. Furthermore, this patch also changes musl to download directly from git. This makes it easier to update musl in the future. The patch custom Add-format-attribute-to-some-function-declarations.patch was assigned a new 400- number. This should avoid confusion since 0xx numbers are usually assigned to backports.
