C11 threads were changed to use struct timespec instead of xtime, and
thrd_sleep got a second argument.
As xtime was replaced with timespec there's a couple of odd bits in the code.
See http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1554.htm and
http://en.cppreference.com/w/c/thread/{thrd_sleep,cnd_timedwait,mtx_timedlock}
Note that cnd_timedwait is spec'd to be relative to TIME_UTC / CLOCK_REALTIME.

We don't have a fall-back declaration of the struct, yet we use it
below and provide a timespec_get() implementation.
I'd imagine you haven't tested this on Windows (hence Jose in CC)?
Right on both counts, as I don't really have a way of testing on Windows.
Quick search suggests that MSVC 2015 was the first one that introduces
the struct and timespec_get.
If we're safe as-is, please add a comment with some details - I'd
imagine Jose had better knowledge in the area.

I'd just drop the hunk mentioning that timespec_get() is part of time.h
I wasn't sure when timespec_get was introduced, so I thought it safer to
keep it around for a while in case we run into systems where time.h
doesn't provide it.
I can add a comment, or remove it entirely if you think that's not a
concern.
Cheers,
Nicolai
Thank
Emil
