I'm not sure if this is a g++ bug or a V2.0 feature. In any case,
similar code worked fine under 1.35.   The compiler complains about
the jump past the initialization point.  In this example, the goto
can be replaced by a continue; in the actual application, the goto 
is used as a continue(3) equivalent (continue with loop 3 levels out),
so no flames about goto's. Please.
