Reverse the change of 1998-04-22. Providing a struct dirent with different members when __USE_FILE_OFFSET64 is defined is asking for trouble. Instead add the necessary LFS magic to the 4.4BSD header. * sysdeps/unix/bsd/bsd4.4/bits/dirent.h: Add LFS definitions. * sysdeps/mach/hurd/bits/dirent.h: Removed. * sysdeps/mach/hurd/readdir64.c: Removed. * sysdeps/mach/hurd/readdir64_r.c: Removed. * sysdeps/generic/bits/mman.h [__USE_MISC] (MAP_ANONYMOUS): Define as alias for MAP_ANON. * stdio/stdio.h (sys_errlist, sys_nerr, _sys_errlist, _sys_nerr): Remove decls. They don't exist at all on the Hurd.
