From 542c6f25327587d5a6bffb8a45b457ec85dcf8e1 Mon Sep 17 00:00:00 2001
From: Florian Weimer <fweimer@redhat.com>

Subject: [PATCH 3/3] configure: Further defang the -Werror check
Incompatible pointer types are actually errors (in the sense
that they are invalid C). Compilers have merely tolerated them as
warnings for backwards compatibility. This is changing with Clang 16
and GCC 14, so relax the check a little.
