package/libs/libbsd/patches/001-handle-systems-missing-sys_cdefs.h.patch

+From 11ec8f1e5dfa1c10e0c9fb94879b6f5b96ba52dd Mon Sep 17 00:00:00 2001
+From: Guillem Jover <guillem@hadrons.org>
+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

package/libs/libbsd/patches/002-fix_function_declaration_protection_for_glibc_already_providing_them.patch

+From 1f8a3f7bccfc84b195218ad0086ebd57049c3490 Mon Sep 17 00:00:00 2001
+From: Guillem Jover <guillem@hadrons.org>
+Date: Tue, 6 Mar 2018 01:39:45 +0100
+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.
