- removed the 'const' from arithb function declarations. it caused

the myriad of warnings people complained about so long.

  after careful consulting & reading I could not find a good reason
  for this const stuff, apart from a sort-of comment to indicate
  this array (matrix) pointer cannot be changed. Well, doh! you
  should not do that with a float mat[][3] anyway!
