inotify: Make this optional on platforms that don't have this interface. mknod, mkfifo etc.: Make these optional on non-Unix platforms. readdir: If d_type field is missing on the platform, set the corresponding field to 'u'. stat: st_blocks and st_blksize are missing on non-Unix platforms, so set these fields to -1 in the corresponding structures.
