Thanks for trying.
I'm not seeing the 'unresolved references' related libncurses.a. I
just see the warnings I first reported. And I'm pretty sure I'm not
getting the whole crash exe compiled statically successfully because
when I try to use it on a different system, crash gives me read errors,
such as:
