commit b5afd2e319b0f06697c83806e85dd15fab508e5b
Author: John Ralls <jralls at ceridwen.us>
Date:   Fri Oct 4 12:26:35 2019 -0700

    Set C and C++ standards the modern Cmake way, and set C++ to C++17.
    
    Boost has to go to 1.67 as well because boost::locale used auto_ptr
    before that and it's been removed from the language in C++17.
