+Subject: [PATCH 1/3] build: fix compatibility with stricter C99 compilers
+
+Fix the following warnings:
+- -Wimplicit-int (fatal with Clang 16)
+- -Wimplicit-function-declaration (fatal with Clang 16)
+- -Wincompatible-function-pointer-types (fatal with Clang 16)
+- -Wint-conversion (fatal with Clang 15)
+- Old style prototypes (K&R, removed from C23)
+
+These warnings-now-error led to misconfigurations and failure to build
+OpenLDAP, as the tests used during configure caused the wrong results
+to be emitted.
+
+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].
