Please don't put essential info in the subject that is not appearing  
in the body description, because the reasoning becomes hard to follow  
(and cc all replies to Help-Bison). Specifically, shift/reduce  
conflicts can sometimes be resolved using operator precedence, %left  
etc.: see Bison manual. Look at the .output file to see which tokens  
that appear immediately before the "." in the conflicting rules. In  
general though there is no such method. I think Bison chooses shifts  
over reduces, and the reduce that comes first in the grammar .y file.
