      If <span class="bold"><strong>Boost.Context</strong></span> uses fcontext_t (the default)
      as its implementation, it must be built for the particular compiler(s) and
      CPU architecture(s) being targeted. Using <a class="link" href="ff/implementations__fcontext_t__ucontext_t_and_winfiber.html#implementation"><span class="emphasis"><em>fcontext_t</em></span></a>,
      <span class="bold"><strong>Boost.Context</strong></span> includes assembly code and,
      therefore, requires GNU as and GNU preprocessor for supported POSIX systems,
      MASM for Windows/x86 systems and ARMasm for Windows/arm systems.

      Because this library uses C++11 extensively, it requires a compatible compiler.
      Known minimum working versions are as follows: Microsoft Visual Studio 2015
      (msvc-14.0), GCC 4.8 (with -std=c++11), Clang 3.4 (with -std=c++11). Other
      compilers may work, if they support the following language features: auto declarations,
      constexpr, defaulted functions, final, hdr thread, hdr tuple, lambdas, noexcept,
      nullptr, rvalue references, template aliases. thread local, variadic templates.
