+From 82098ab9b853c33ee8ade61c9510b295cc696de1 Mon Sep 17 00:00:00 2001
+From: Peter S. Mazinger <ps.m@gmx.net>
+Date: Wed, 09 Mar 2011 08:23:48 +0000
+Subject: guard *_chk() related stuff with UCLIBC_HAS_FORTIFY
+
+Guard x86_64 memset_chk/memcpy_chk be guarded by UCLIBC_HAS_FORTIFY.
+Compile ssp.c if one of SSP/FORTIFY is defined.
+Guard __chk_fail() with UCLIBC_HAS_FORTIFY and move its prototype to libc-internal.h.
+Disable _FORTIFY_SOURCE if UCLIBC_HAS_FORTIFY is not set.
+
+The config option itself is omitted on purpose,
+headers need to be reviewed and generic *_chk() functions need to be first provided.
+
+Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>
