-Subject: [PATCH] Fix ABI demangling for the GCC 5.x case.
-
-When glog is compiled with gcc-5.2 in cxx11 ABI mode, it barfs about unmangled symbols.  This patches it getting inspiration from binutils and demangle.cc itself, although it may be totally wrong or maybe have to use ParseAbiTag in more places.  I haven't read the spec for the symbols, though.
-
-This patch makes the demangle unit test pass correctly.
