I wasn't counting that as a conflict.  Sorry, I should have made that
clear.  My quotation above is rule 4 of how to apply precedences and
associativities.  Rules (1) covers priorities, and has the expected
and traditional effect.

The standard also says:

"Conflicts resolved by precedence or associativity shall not be
 counted in the shift/reduce and reduce/reduce conflicts reported by
 yacc on either standard error or in the description file."
