From a6817677a42d1294f1a3ce7b9f46b10ec557ddfa Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Sun, 1 Apr 2018 15:23:59 +0200 Subject: [PATCH] configure.in: Allow to override the INADDR_NONE check Prevent configure script from trying to run programs in a cross compilation environment to check if INADDR_NONE is defined. In the context of Buildroot, INADDR_NONE is always defined. The snort package will set have_inaddr_none=yes in SNORT_CONF_ENV.
