Subject: * ext/bigdecimal/bigdecimal.c (rb_rational_num): add fallback
 function   for rubies lower than 2.2.0.

* ext/bigdecimal/bigdecimal.c (rb_rational_den): ditto.

* ext/bigdecimal/extconf.rb: check the existences of struct RRational,
  rb_rational_num, and rb_rational_den.

* ext/bigdecimal/bigdecimal.bundle: bump version.
