Fix build failure caused by use of the deprecated readdir_r(3) while building with -Werror=deprecated-declarations Patch copied from upstream source repository: https://github.com/daveol/ola/commit/9d8575ff38f76df698ea8889e07a3dee8f21bd68 From 9d8575ff38f76df698ea8889e07a3dee8f21bd68 Mon Sep 17 00:00:00 2001 From: Dave Olsthoorn <dave.olsthoorn@gmail.com> Date: Wed, 2 Mar 2016 11:22:17 +0100 Subject: [PATCH] Use readdir instead of readdir_r This replacec the use of readdir_r with readdir since readdir seems to be both dangarous and deprecated in newer versions of glibc.
