Revert to original debugging code and wrap any variabled used only 

within an ASSERT with the ASSERTV macro which will ensure it will
be removed when the ASSERTs are commented out.  This makes gcc much
happier, makes the variables usage explicit, and removes the need
for the compiler to detect it is unused and do the right thing.
