Fri Jul 14 12:49:50 2000 Yukihiro Matsumoto <matz@netlab.co.jp>
* io.c (argf_eof): need to check stdin, when next_p == -1.
* io.c (read_all): use io_fread() instead of fread(3).
* io.c (io_reopen): should clearerr FILE if fd < 3.
* re.c (rb_reg_match_m): the result is exported, so it should be
declared as busy.
* eval.c (rb_eval): should preserve errinfo even if return, break,
etc. is called in rescue clause.
