+Subject: [PATCH] configure: fix -Wimplicit-function-declaration,
+ -Wimplicit-int
+
+Clang 16 makes -Wimplicit-function-declaration and -Wimplicit-int errors by default. Unfortunately,
+this can lead to misconfiguration or miscompilation of software as configure
+tests may then return the wrong result.
+
+For more information, see LWN.net [0] or LLVM's Discourse [1], the Gentoo wiki [2],
+or the (new) c-std-porting mailing list [3].
