From 0e6295128c605f1cf41d897c53e6e23e893a6ffa Mon Sep 17 00:00:00 2001 From: Jaco Kroon Date: Mon, 15 May 2023 14:50:36 +0200 Subject: [PATCH] configure: fix test code to match gethostbyname_r prototype. (#75) 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.
