+From 8810f2643c9372a8083272dc1fc157427646d961 Mon Sep 17 00:00:00 2001
+From: Khem Raj <raj.khem@gmail.com>
+Date: Wed, 10 Aug 2022 17:16:23 -0700
+Subject: [PATCH 1/2] configure: Specify correct function signatures and
+ declarations
+
+Include needed system headers in configure tests, this is needed because
+newer compilers are getting stricter about the C99 specs and turning
+-Wimplicit-function-declaration into hard error e.g. clang-15+
