I have got a local patch implementing C11 for NetBSD.

I need to refresh it a bit as the right approach is to embed it into
libc and make it work once upon a program is linked with -lpthread. My
integration was still incomplete as my work was interrupted by
libpthrad(3) bugs (now solved).

A direct user from base for C11 threads is (at least used to be) MESA.

I use the following types:

+/* ISO/IEC 9899:201x 7.26.1/4 */
+typedef pthread_cond_t	  cnd_t;
+typedef pthread_t	  thrd_t;
+typedef int		  tss_t;
+typedef pthread_mutex_t	  mtx_t;
+typedef void		(*tss_dtor_t)	(void *);
+typedef int		(*thrd_start_t)	(void *);
+typedef	pthread_once_t	  once_flag;

It would be nice to get it for -9.
