Re: doubts with shift-reduce and nonterminals

You look at the tokens immediately before and after the "." of a  
shift/reduce conflicting rules pair (as in the file '.output'), and  
set token precedences between those, which may resolve the conflict,  
if you are lucky Check out the calculator example in the Bison manual.
