From d67d6b4f981db9612d808bd723176a1d2996d53a Mon Sep 17 00:00:00 2001 From: Alexander Kanavin Date: Mon, 17 Jan 2022 13:21:32 +0100 Subject: [PATCH] configure.ac: check getprotobynumber_r with AC_TRY_LINK AC_TRY_COMPILE won't error out if the function is altogether absent (e.g. on linux musl C library), the test needs to link all the way.
