ruby--ruby/prec.c
matz b47a99485b * parse.y (yylex): ternary ? can be followed by newline.
* eval.c (rb_f_require): should check static linked libraries
  before raising exception.

* array.c (rb_ary_equal): check identiry equality first.

* string.c (rb_str_equal): ditto.

* struct.c (rb_struct_equal): ditto.

* numeric.c (Init_Numeric): undef Integer::new.

* eval.c (rb_eval): NODE_WHILE should update result for each
  conditional evaluation.

* eval.c (rb_eval): NODE_UNTIL should return last evaluated value
  (or value given to break).
