I am sure http://bb.pgr.jp/ has been C++11 ready.

  - gcc-4.4 and msc16 were dropped.
  - Linux builders use gcc-4.7.2 (SL based homebrew)
  - Introduced mingw-w64-gcc-4.8.1 (for now targeting x64)
  - All CMake builders are configured with LLVM_ENABLE_CXX11=ON.
  - configure will run as-is. expected to follow default option.

a few new builders will come. Working in progress.
