The patchset should not change libc/libpthread functional, although object changes are expected (since now internal symbols are used instead) and final exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread usage of __mmap{64}, __munmap, __mprotect).

Since I do not have access to the official ISO documentation I would ask if there any deviation from the draft to final doc regarding threads.h please let me know. However based on Joseph's comments on a old thread [2] I would expect to N1570 and final standart to not have any technical differences. Mostly of the definition required are defined based on POSIX counterparts, such as thrd_t (pthread_t), once_flag (pthread_once_t), tss_t (pthread_key_t). The mut_t and cnd_t is also based on internal pthreads fields, but with a distinct internal layout to avoid possible issues with code interchange (such as trying to pass POSIX structure on C11 functions and to avoid inclusion of pthread.h). The idea is to make it possible to share POSIX internal implementation for mostly of the code making adjust where only required. For mostly symbol implementations, direct POSIX pthread internal calls are used with some exceptions: 1. thrd_start uses pthread_create internal implementation, but changes how to actually calls the start routine. This is due the difference in signature between POSIX and C11, where former return a 'void *' and latter 'int'. To avoid calling convention issues due 'void *' to int cast, routines from C11 threads are started slight different than default pthread one. Explicit cast to expected return are used internally on pthread_create and the result is stored back to void also with an explicit cast. 2. thrd_sleep uses nanosleep internal direct syscall to avoid clobbering errno and to handle expected standard return codes. 3. thrd_yield also uses internal direct syscall to avoid errno clobbering. Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, hppa-linux-gnu, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, tile{pro,gx}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu.
