This thread has some real silly stuff in it. Especially "is there a
machine still in use with different function/char/other pointers?"

The IBM PC when building using any 16 bit compiler using either Medium
or Compact Model has different size function and data pointers.

I think there are at least a FEW of those computers still out there.
