Right. That was my problem - TCC only exposed it. I've rearranged the
declarations and definitions as explained and it now links.

Following the example in K&R 2nd ed., Chapter 1.10. However, I didn't
completely understand the chapter (that much is obvious now that I
reread it) and therefore got tangled in the web of my own making.

Thank you people! It now works. If all goes as planed, the
program/library I am working on will be somewhere under
https://gitorious.org/~akuktin/ in a few weeks. Otherwise, one can
google "nbworks".
