OK.  This is a followup.

What happened, and dummy me, I didn't do a "make mrproper" before I made 
changes to the kernel.  I ended up copying the config file I had copied 
from a good compile into the .config file (after the make mrproper). 
Then I put in one change at a time (this is the proper way to do it). 
After I got all of my changes in, each time doing a "make mrproper", it 
worked. The settings I had originally were correct, only the "make 
mrproper" was not done, so it didn't compile correctly.

So, like the book says, it is very important to do a 'make mrproper'.

 From now on I will always do the "make mrproper" first.

Thanks for the help.
