* eval.c (rb_eval): too many line trace call. (ruby-bugs PR#1320)

* numeric.c (flo_to_s): tweak output string based to preserve
  decimal point and to remove trailing zeros.  [ruby-talk:97891]

* string.c (rb_str_index_m): use unsigned comparison for T_FIXNUM
  search.  [ruby-talk:97342]

* hash.c (rb_hash_equal): returns true if two hashes have same set
  of key-value set.  [ruby-talk:97559]

* hash.c (rb_hash_eql): returns true if two hashes are equal and
  have same default values.

* string.c (rb_str_equal): always returns true or false, never
  returns nil. [ruby-dev:23404]

* io.c (rb_io_reopen): should use rb_io_check_io().
