GCC prerequisites for building LLVM head?
...Linux setup that uses v4.9.3.
The 'std::to_string' functions are provided in a block that is conditionally included as follows (line #2847 in my copy):
#if __cplusplus >= 201103L && defined(_GLIBCXX_USE_C99)
#include <ext/string_conversions.h>
namespace std _GLIBCXX_VISIBILITY(default)
{
_GLIBCXX_BEGIN_NAMESPACE_VERSION
The test '__cplusplus >= 201103L' evaluates true in all previous cases, so it would appear that '_GLIBCXX_USE_C99' is not being defined - I can add this explicitly when I am configuring LLVM with CMake, but it seems a bit stran...

GCC prerequisites for building LLVM head?
Is there is minimum required version for GCC to build LLVM from the head
revision?
I have GCC v4.9.3, but 'Tools/sancov/sancov.cc' won't build because
'std::to_string' does not exist. When running CMake it did not flag GCC
v4.9.3 as too old, and it is passing the '-std=gnu++11' option, but
apparently this version of GCC is not fully C++ 11 compliant, or at least
