4Subject: [PATCH] configure.in: Allow to override the INADDR_NONE check
5
6Prevent configure script from trying to run programs in a cross
7compilation environment to check if INADDR_NONE is defined.
8
9In the context of Buildroot, INADDR_NONE is always defined.
10The snort package will set have_inaddr_none=yes in
11SNORT_CONF_ENV.
