+This patch enables building gcc-4.6.4 using gcc-2.95.3 and glibc-2.2.5
+
+ * Tweak Makefile to allow overriding NATIVE_SYSTEM_HEADER_DIR using #:makeflags
+ * Add missing limits.h include.
+ * Add SSIZE_MAX define. The SSIZE_MAX define has been added to Mes
+ upstream and can be removed with the next Mes release.
+ * Remove -fbuilding-libgcc flag, it assumes features being present from a
+ newer gcc or glibc.
+ * [MES_BOOTSTRAP_GCC]: Disable threads harder.
+
+Upstream status: not presented upstream.
