+       * io/file_pos.c (st_rewind): Handle regular and special files
+       identically.
+       * io/intrinsics.c (fseek_sub): Don't check whether we think the
+       file is seekable, just do what the caller says.
+       * io/transfer.c (skip_record): First try to seek, then fallback to
+       reading and throwing away what we read.
+       * io/unit.c (update_position): Don't check whether file is
+       seekable, just try to do what we're told.
+       (unit_truncate): Likewise.
+       * io/unix.c (struct unix_stream): Remove special_file flag.
+       (buf_flush): Remove code for handling unseekable files.
+       (buf_seek): Likewise.
+       (fd_to_stream): Use buffered IO only for regular files.
+       (file_length): Remove is_seekable() call.
+       (is_seekable): Remove function.
+       (is_special): Likewise.
+       * io/unix.h: Remove prototypes for is_seekable and is_special.
