From 08617a8d29ee22831175697555558fec8f52772c Mon Sep 17 00:00:00 2001
From: Samuel Martin <s.martin49@gmail.com>
Date: Sun, 1 Jun 2014 16:05:04 +0200
Subject: [PATCH] auto/unix: make sys_nerr guessing cross-friendly
This patch replaces the default sys_nerr runtest with a test done at
buildtime.
The idea behind this buildtime test is finding the value of the ERR_MAX
macro if defined, or the EHWPOISON (which is currently the last errno)
otherwise.
