Earlier versions of javac would silently insert method declarations into the
class file of the abstract class - si-called "Miranda methods", see e.g.
Stricly speaking this was a bug in early Sun VMs, and you can still get later
versions of javac to operate the work-around by specifying a 1.1 target. But
the correct place to fix it is in Kaffe - either you modify the way you
search the class hierarchy for inherited methods, or you hack the internal
class structures to emulate what older compilers were doing. In Wonka we took
the latter route, but it's not the only or even necessarily the best way.
