You can't do this if you have sources that you would like to sell.
If you have sources that build stuff for several machines, you don't
want to give them all away. Here is where you unifdef what you
don't want to give away. Also ccp pulls in include files, and 
expands #defines. How would you like AT&T to give you sources
with no include files or only octal and hex numbers for all the
masks and parameters.
