From 79468a12c3533720c938731a8b7728ba4ff5a326 Mon Sep 17 00:00:00 2001
From: Jaco Kroon <jaco@uls.co.za>
Date: Wed, 10 May 2023 23:13:17 +0200
Subject: [PATCH] configure: fix test code to match gethostbyname_r prototype.
This enables the test to work with CC=clang.
Without this the test for 6 args would fail with:
utils.c:99:12: error: static declaration of 'gethostbyname_r' follows non-static declaration
static int gethostbyname_r (const char *name, struct hostent *ret, char *buf,
^
/usr/include/netdb.h:177:12: note: previous declaration is here
extern int gethostbyname_r (const char *__restrict __name,
^
Fixing the expected return type to int sorts this out.
