-From 11ec8f1e5dfa1c10e0c9fb94879b6f5b96ba52dd Mon Sep 17 00:00:00 2001
-From: Guillem Jover <[e-mail]>
-Date: Tue, 6 Mar 2018 01:41:35 +0100
-Subject: Handle systems missing <sys/cdefs.h>
-
-This is a non-portable header, and we cannot expect it to be provided by
-the system libc (e.g. musl). We just need and rely on declaration that
-we have defined ourselves in our own <bsd/sys/cdefs.h>. So we switch to
-only ever assume that.
-
-Fixes: https://bugs.freedesktop.org/105281

-Subject: Fix function declaration protection for glibc already providing them
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-On non-glibc based systems we cannot unconditionally use the
-__GLIBC_PREREQ macro as it gets expanded before evaluation. Instead,
-if it is undefined, define it to 0.
-
-We should also always declare these functions on non-glibc based
-systems. And on systems with a new enough glibc, which provides these
-functions, we should still provide the declarations if _GNU_SOURCE
-is *not* defined.
