I think to be of any value, the notices have to be 'visible', not hidden
at the end of the file.  To do this, you need to arrange for text constants
to be in the statup code.

Of course, if you are laying traps to mark your code for identification,
visibility is not an issue, but then just running the executable through
'ld' again will probably neatly trim off your addition.

Yes, I know that no 'written' copyright notice is needed for the work to
be copyrighted, but that isn't the issue here...
