+Subject: [PATCH] no host includes
+
+With this patch gcc bails out if you include a host include path into
+the searchlist (-I). This patch is not intended for upstream and was
+inspired by
+
+http://www.openembedded.org/repo/org.openembedded.dev/packages/gcc/gcc-4.1.1/zecke-no-host-includes.patch

+Subject: [PATCH] gcc/i386: use pure64 CLFS patch
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is a modified version of
+http://trac.cross-lfs.org/browser/patches/gcc-4.6.0-pure64-1.patch to use /lib
+instead of /lib64 for x86_64.
+This will only work as generic patch, if we do _not_ build multilib x86
+toolchains.
