commit 14f81bc47a4c462ccc609fce74feb014185e2bf9 Author: Sam James <sam@gentoo.org> Date: Thu Feb 9 23:17:53 2023 +0000 ITS#10011 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].
