The cnd_timedwait function has been converted to support 64 bit time. It was also necessary to provide Linux specific copy of it to avoid problems on i686-gnu (i.e. HURD) port, which is not providing pthread_cond_timedwait() supporting 64 bit time. Moreover, a linux specific copy of thrd_priv.h header file has been added as well. The cnd_timedwait is a wrapper on POSIX threads to provide C11 standard threads interface. It directly calls __pthread_cond_timedwait64(). Build tests: ./src/scripts/build-many-glibcs.py glibcs Reviewed-by: Alistair Francis <alistair.francis@wdc.com>
