	* version 1.0-971021

Mon Oct 20 12:18:29 1997  WATANABE Hirofumi  <[email protected]>

	* ruby.c (load_file): wrong condition for #! check with -x.

	* file.c (file_s_dirname): did return "" for "/a".

Fri Oct 17 14:29:09 1997  Yukihiro Matsumoto  <[email protected]>

	* bignum.c (bigadd): some undefined side effect order assumed.
