thrd_sleep, mtx_timedlock, and cnd_timedwait take a struct timespec, whose layout follows time_t. libmingwex.a was compiled for 32-bit time_t only, so x86 programs built with 64-bit time_t read garbage timeouts. The plain names keep the 32-bit ABI so existing objects still link correctly, and threads.h redirects 64-bit time_t callers to new *64 variants. x64 is unchanged.
