2002-04-18* re.c (rb_reg_expr_str): should treat backslash specially inmatz
escaping. * io.c: complete off_t handling; missing argument for fptr_finalize(); polished rb_scan_args call. * dir.c: wrap multi-statment macro by do { } while (0) * eval.c, numeric,c, sprintf.c, util.c: ditto. * bignum.c (rb_big_eq): check `y == x' if y is neither Fixnum, Bignum, nor Float. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@2382 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
