[config] msvc-14.1 and C++14 constexpr
So.... MSVC-14.1 (2017) sort of supports C++14 constexpr. However, it is also prone to internal compiler errors, and currently does not compile config_test.cpp unless we set BOOST_NO_CXX14_CONSTEXPR. Does anyone have a view on which way this macro should be set? Thanks, John. --- This email has been checked for viruses by AVG. http://www.avg.com

Please report constexpr ICEs now (with preprocessed repros), so we can fix them for the first VS 2017 toolset Update. Report A Problem in the IDE is a convenient way. As a special favor to Boost developers, I will file constexpr ICEs in our internal database, if you send me a zipped preprocessed repro and corresponding command line to compile the preprocessed file. Thanks, STL

For the 1.64.0 release, at least, I think the safer thing is to define BOOST_NO_CXX14_CONSTEXPR. Glen

Even C++11 constexpr doesn't quite work. I just tried mp11's tests and the constexpr implementation of https://github.com/pdimov/mp11/blob/master/include/boost/mp11/detail/mp_coun... still doesn't compile.
