+Subject: [PATCH] configure: Add needed system headers in checks
+
+Newer compilers throw warnings when a funciton is used with implicit
+declaration and enabling -Werror can silently fail these tests and
+result in wrong configure results. Therefore add the needed headers in
+the AC_TRY_LINK macros
+
+	* configure.ac: Add missing system headers in AC_TRY_LINK.
+
+Upstream-Status: Submitted [https://lists.gnu.org/archive/html/screen-devel/2022-08/msg00000.html]
