cygwin で 2.6.0-preview2 の mjit をとりあえずで動かせるようにしてみました。
(コンパイルできるだけのレベル)

cygwin だと必ず false になるという都合で
pthread_attr_setscope(&attr, PTHREAD_SCOPE_SYSTEM) == 0 を
コメントアウトしてますが、この関数が必須なら cygwin で mjit は
動かさない方が良いということだと思います。

mjit.c: initial cygwin support

thread_pthread.c: Drop pthread_attr_setscope usage. It seems that,
at least on Linux and macOS, PTHREAD_SCOPE_PROCESS is not supported
and thus PTHREAD_SCOPE_SYSTEM should be used by default.

Let's just stop calling this until we find some platform that needs
pthread_attr_setscope(&attr, PTHREAD_SCOPE_SYSTEM).
