The posix threading model enabled toolchains do not interfere or prevent
the use of Win32 threads. In fact, C++ std::thread is a wrapper of a
wrapper (GCC's internal gthread) of a wrapper (winpthreads) of Win32 native
threading primitives.
The best way is actually a configure-time check for std::thread
functionality (e.g. test a simple join() call). I know of no preprocessor
macro.
