  log: "lint: resolve shift/reduce conflicts for unary expressions\n\nThe grammar
    rule 'term' was ambiguous since both the prefix and postfix\nincrement operators
    were listed with the same precedence.  The\nexpression '++x++' was parsed as '++
    (x++)', as expected, since\nconflicts resolve towards shift.\n\nResolve these
    conflicts by structuring the grammar as in C99, with the\nGCC extension of statement-expressions.
    \ The resolved conflicts are:\n\n134: shift/reduce conflict (shift 161, reduce
    347) on T_LBRACK\n134: shift/reduce conflict (shift 162, reduce 347) on T_LPAREN\n134:
    shift/reduce conflict (shift 163, reduce 347) on T_POINT\n134: shift/reduce conflict
    (shift 164, reduce 347) on T_ARROW\n134: shift/reduce conflict (shift 165, reduce
    347) on T_INCDEC\nstate 134\n\tterm : term . T_INCDEC  (335)\n\tterm : term .
