+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.

+Refresh for 1.8.0.
