Check for baseline language coverage in the compiler for the C++11 standard; if necessary, add switches to CXX and CXXCPP to enable support.
This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX macro with the version set to C++11. The two optional arguments are forwarded literally as the second and third argument respectively. Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for more information. If you want to use this macro, you also need to download the ax_cxx_compile_stdcxx.m4 file.
