[ a bit alarmed... ]  This is only going to be an acceptable solution
if you can explain *exactly why* it works.  The general story with
associativity/precedence declarations is that you are making bison
resolve ambiguous situations in particular ways.  If you don't have a
100% clear understanding of what the ambiguity is and why this is the
right way to resolve it, you are probably creating a bigger problem.
