+Subject: [PATCH] Add missing includes to configure script
+
+This is needed for gcc 14 and clang 16 as they both make implicit
+function definitions a hard error.  In a configure script, this means
+these tests will switch from passing to failing, which likely means
+features will get unintentionally flipped as configure now thinks you
+don't have support.
