+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.
