llvm dev - Dec 2018 - Error: ISO C++17 does not allow 'register' storage class specifier [-Wregister], when building Boost 1.69.0

When trying to build Boost using LLVM, I had this error:
"
error: ISO C++17 does not allow 'register' storage class specifier
[-Wregister]
"
I attached the project-config.jam file I used to this message.  Someone please
help me out (if there's someone on here who can).

This seems a better question for cfe-dev or cfe-users

Yes, this keyword is no longer valid starting from C++17:
     https://en.cppreference.com/w/cpp/keyword/register

I realize that the "why" probably doesn't help you move forth with
your
problem, so here are a couple suggestions how to get over it:

  * Build Boost in C++14 mode with -std=c++14
  * Cut out "register" from the Boost source and rebuild
  * Try a newer Boost version, it may have been fixed
