- The rename-directory-for-backup heuristic now checks the
  DEL_FORCE_RECURSE flag, not the zap_dir variable.  We also set
  the flag when we recurse so that only the root dir of a deleted
  hierarchy can be missing the flag (and thus be a call from the
  generator).

to rename a directory over a file or visa versa, try to handle it.

older versions: (1) we no longer complain if excluded files
sticking around cause us to not be able to remove a subdir, and
(2) we output the name of the removed subdir after it has been
successfully removed.

- Added AC_C_LONG_DOUBLE for snprintf.c code.
- Got rid of unneeded ino_t check.

- No need to separately test for (make_backups && !backup_dir)
  because omit_dir_times is now set under those circumstances.

- Made delete_missing() static.

- Only send an explicitly specified -O (--omit-dir-times)
