From ccf988e51087cee521b32df646de4ce3ef291de1 Mon Sep 17 00:00:00 2001 From: "Bradley T. Hughes" Date: Wed, 13 Jun 2012 13:23:53 +0200 Subject: [PATCH] clang: Do not use libstdc++ when C++11 is enabled We expect that the C++ library also supports C++11 when the compiler says it does as well. When using clang with libstdc++, the library has no C++11 support or headers, so we cannot use, for example, #include .
