I know what you mean. And then there are comments such as this one:

  /* This form didn't work with Zortech 386 compiler */
  /* value = Sqr((sin(x)+sin(y)+sin(z))/3); */
  /* So we break it down. */

I think we can move past this now... right?

I hope to slowly work my way through it and find more to fix.

Yes, that's true, I admit it. The sad part is that since I have trouble
comprehending other parts of the code, this is about as big a contribution
as I can make. :(
