"Miranda methods" occur when an abstract class inherits a declaration from an
interface but does not redeclare or define that method.

When this occurs, gcj emits a vtable entry into the abstract class so that
virtual calls to the method, made on the abstract class, can work correctly.

gcjh is not aware of this, however, and the .h file it generates is inconsistent
with the vtable emitted by gcj.
