In the "Compressed rb_singleton_class()" section, there is a line:
701 if (FL_TEST(RBASIC→klass, FL_SINGLETON) &&
However the correct one should be:
701 if (FL_TEST(RBASIC(obj)->klass, FL_SINGLETON) &&
(from http://i.loveruby.net/ja/rhg/book/class.html).
FL_TEST(<acronym title="obj"><span class="caps">RBASIC</span></acronym>
The html source shows that the obj term becomes part of an <acronym> tag, seems like wrong generated.
