In that example nothing, but in general bracketing defines is a good thingas it
avoids problems with operator precedence doing unexpected things
to your code.
eg.

        // define T1 & T2 to both equal 3
      #define T1   1+2
      #define T2   (1+2)

    a=5+T1*3;        // a=5+1+2*3=12
    b=5+T2*3;       //  a=5+(1+2)*3=14;

a & b will not be equal.
This is because * has a higher precedance than +.

Hope that helps....
