Hmm... Ok, they both bind to the stdin file descriptor (0). I've made this
mistake before and obviously 'informed' myself with sketchy info. I'm very
sorry for the (rotten) noise, but I'm glad my head's out of the sand (again,
for now). Nasty.

Anyway, a single program *can* indeed work with both protocols. This
requires only a trivial addition to the interface and only minor changes
internally. However, it does make the selective header/implicit typedef's
strategy seem much more fickle.

Noted. Providing two different port numbers is much simpler than providing
two versions of the program.

That's a large pool of use-cases that needs to be catered for, no doubt.
Using a FastCGI daemon as an intermediate server/filter/load-balancer/etc.
to other back-end processes is a very reasonable use-case, for example.

Thanks for your persistence, Martin, that was no small brain-wrong you
pointed out. :)
