+From 5ac5885d35257888d0e4a9dda903405314f9fc84 Mon Sep 17 00:00:00 2001
+From: Khem Raj <raj.khem@gmail.com>
+Date: Wed, 10 Aug 2022 17:53:13 -0700
+Subject: [PATCH] configure: Add correct system headers and prototypes to tests
+
+Newer compilers e.g. clang-15+ have turned stricter towards these
+warnings and turned them into errors which results in subtle failures
+during build, therefore make the testcases use the needed headers and
+modern C
+
+Upstream-Status: Inactive-Upstream
