OK.  I was not sure, as the code is older than that.  But I guess the copyright 
goes by the file, not the code...

Yes, how could I forget!

Good point.  Of all people I should have remembered that one ;-)

It seems that it may need some clean-up.  But you are right, I am just moving 
code and I like to do the least possible changes on that pass.

One of us should take a look and see if there is something else. It will be 
easier to maintain it as it becomes the only disassembler code instead of one of 
many.


Thanks for looking at this.  I will make the changes and check it in.

Fernando
