 * The GNU versions of the MAX and MIN macros do two things better than

 * the old versions:

 * 1. they are more optimal as they only evaluate a & b once by creating a

 *    a variable of each type on the local stack.

 * 2. they fix potential errors due to side-effects where a and b were

 *    evaluated twice, i.e. MIN(i++,j++)

 * @note b could be cast to a's type, to help with usage where the code

 *       compares signed and unsigned types.
