I can confirm that narrow-to-region in its new form is not compatible
with old byte code.  The reason: old byte code puts 2 values on the byte
stack, the new byte code implementation expects 3 values on the stack.
What the third value will be is whatever happenes to be there.  And what
happens when it finds an integer or marker is also less desirable.

That's unrelated: It was an error in nextstep/Makefile.in by which Emacs
didn't have a .pdmp, and hence didn't have a file-name-sans-extension
(bug#56853).
