[Boost-users] Semantic Compiler Errors (general question)

I have included and linked the latest Boost C++ library into my build. I
tested the library beforehand. However, when simply including the header
files in a C++ actor class in my Unreal game project, I get errors like:

Warning Example:

    Error boost/config/stdlib/dinkumware.hpp(99) : warning C4668:
'_HAS_NAMESPACE' is not defined as a preprocessor macro, replacing with '0'
for '#if/#elif'

Error Examples:

    Error boost/intrusive/slist.hpp(1926) : error C4003: not enough actual
parameters for macro 'check'

    Error boost/intrusive/slist.hpp(1926) : error C2062: type 'void'
unexpected

It looks like there is some strict/unsupported semantic issues with the
compiler that is being used. How do I fix this?

I am on Windows with VS 2017.

Sample programs compile fine with just

    cl /EHsc /I boost_1_64_0 test_game.cpp /link
/LIBPATH:"F:\boost_1_64_0\stage\lib"

Why would the compiler not work from within Unreal?

Thanks, Regards,
James
