+Subject: [PATCH] Show GNU unique symbols as provided symbols
+
+Upstream-Status Submitted
+
+GNU Unique symbol is a GNU extension employed by new version of GCC
+by default. Even Standard C++ library in GCC 4.9 provides some symbols,
+such as _ZNSs4_Rep20_S_empty_rep_storageE in this binding type instead
+of ELF standard weak binding.
+This patch adds support of this new binding type to mklibs-readelf.
