(Re-included the boost ML)

With the -d2 option added, this is what I see:

I do see -std=c++14 in there.

As for your second question, why would building and running
config_info help? I'm cross compiling, so I can't run this on Windows.
If you could provide explicit instructions so I properly understand
what you want me to do, that would be ideal.

Thanks.
