Cygwin C11 threads Implementation

[Joel Sherrill]

Hi

In looking at the C11 threads.h header to see how Cygwin defined thrd_t in
comparison to RTEMS, I noticed that at least in the version of Cygwin I
have installed, machine/threads.h
is missing and there is no typedef for thrd_t in /usr/include.

RTEMS uses the FreeBSD implementation of these services and I would think
Cygwin
could also.

Is this functionality missing or am I missing something?
