 Yes, and the worst thing is that it wasn't done intentionally, I must have
just used a wrong version of Boost when I made r4135.

    This skips the test for the header using the preprocessor and only uses the

    Build lmi in C++11 mode when using configure

    Just use the AX_CXX_COMPILE_STDCXX() macrom from the autoconf macro archive 
    ensure that we use the compiler options enabling C++11 for building our
