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.
