[section:requirements Requirements]

If __boost_context__ uses fcontext_t (the default) as its implementation,
it must be built for the particular compiler(s) and CPU architecture(s)
being targeted.
Using [link implementation ['fcontext_t]], __boost_context__ 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.

[note MASM64 (ml64.exe) is a part of Microsoft's Windows Driver Kit.]

[important Please note that `address-model=64` must be given to bjam command
line on 64bit Windows for 64bit build; otherwise 32bit code will be generated.]

[important For cross-compiling the lib you must specify certain additional
properties at bjam command line: `target-os`, `abi`, `binary-format`,
`architecture` and `address-model`.]

[important Windows using fcontext_t: for safe SEH the property 'asmflags=\safeseh' must be specified at
bjam command line.]

[important Windows using fcontext_t: turn off global program optimization (/GL) and change /EHsc (compiler
assumes that functions declared as extern "C" never throw a C++ exception) to /EHs (tells
compiler assumes that functions declared as extern "C" may throw an exception).]

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.
