 The \c{build2} toolchain requires a C++14 compiler. From the commonly-used

+options, GCC 4.9, Clang 3.4, and MSVC 14 (2015) Update 3 or any later versions
 of these compilers should work. Note also that the C++ compiler that you use

 (which cannot build \c{build2}), it is perfectly fine to get a minimal MinGW
 toolchain and use that to build \c{build2}; you will still be able to use MSVC
 to build your own code.
