I didn't reference the web site for the polynomial, just for background.
To be honest, I'm not sure what the polynomial is.  As the comments
explain, the algorithm I used is precisely taken from gdb, in remote.c,
and is intended to produce the same result.  Does anybody on the gdb
side know the polynomial or any other information?
