 Yes, using an old version of DejaGNU will merely imply the old semantics 
(i.e. folding the "break" and "continue" exceptions into a mere "return") 
enforced at the lower level by remote_expect; we should therefore not rely 
on correct operation of the exceptions until we've decided we require at 
least DejaGNU 1.5 (in a few years' time I suppose).

 Obviously nothing prominent relies on the old semantics within our test 
suite or the switch would have caused regressions.  I could have missed an 
obscure architecture-specific test case of course or some failure paths 
that are not triggered for successful runs (for obvious reasons these are 
more error prone as they are hopefully ;) less regularly tested than the 
corresponding success paths).  Either of which should be fixed in a 
backward compatible manner by replacing "break" or "continue" with 
"return" where appropriate.

 Applied now, thanks for the review.
