+From cd5e920572eabc54dc7350c41ca172b49e48ac1a Mon Sep 17 00:00:00 2001
+From: Eli Schwartz <eschwartz93@gmail.com>
+Date: Sun, 7 Jul 2024 21:38:29 -0400
+Subject: [PATCH] include lots of headers to pass the basic c99 sniff test
+
+Including configure checks, which currently emit broken results.
+
+And in one case, include config.h early enough to do something.
