From d89a938f48e97b5770509d53c5478c5c3008d6e8 Mon Sep 17 00:00:00 2001
From: Bernd Kuhls <bernd.kuhls@t-online.de>
Date: Sat, 27 May 2017 17:53:33 +0200
Subject: [PATCH 1/1] Fix static linking with libsndfile
libsndfile and audiofile both contain mixXX functions in their alac
code which lead to symbol name clashes when apps like mpd try to
statically link to both audiofile and libsndfile at the same time.
This patch renames these functions to avoid the problem which was
detected by the buildroot autobuilders:
http://autobuild.buildroot.net/results/799/7997ccd698f03885f98d00bd150dc3a578e4b161/
Patch sent upstream: https://github.com/mpruett/audiofile/pull/45
Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de>
