* sysdeps/mach/hurd/fork.c (LOSE): Put `goto lose' in dead code
so the label is not considered unused. * sysdeps/mach/hurd/pwrite64.c: New file. * sysdeps/mach/hurd/pread64.c: New file. * sysdeps/mach/hurd/pread.c (__libc_pread): Define this name, with __pread as an alias. * sysdeps/mach/hurd/pwrite.c (__libc_pwrite): Define this name, with __pwrite as an alias. Implement POSIX "shared memory objects" as regular files residing in the /var/run/shm/ directory. This works on any system that supports _POSIX_MAPPED_FILES, to make it also support _POSIX_SHARED_MEMORY_OBJECTS. * sysdeps/posix/shm_open.c: New file. * sysdeps/posix/shm_unlink.c: New file. * sysdeps/mach/hurd/bits/posix_opt.h (_POSIX_SHARED_MEMORY_OBJECTS): Define it. * rt/aio_notify.c (__aio_notify_only) [! _POSIX_REALTIME_SIGNALS]: Use raise instead of __aio_sigqueue.
