+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.
