+Subject: [PATCH] config: Fix -Wimplicit-int, -Wstrict-prototypes (Clang 16)
+
+Followup to be8c977d320ed40cacb322658d4ceba5e583b3a6.
+
+Clang 16 makes -Wimplicit-int error by default.
+
+Unfortunately, this can lead to misconfiguration or miscompilation of software as configure
+tests may then return the wrong result.
+
+We also fix -Wstrict-prototypes while here as it's easy to do and it prepares
+us for C23.
+
+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].
