<mutex>, <condition_variable>, and <future>. <atomic> has always worked and
will continue to work without posix threading.

problem for most people, but it does make even C code not using pthreads
that depends on libgcc (pretty much all code compiled by gcc depends on
libgcc), depend on winpthreads as well.
