Good work. Would you mind if I put a link to it from the libwww NEWS page?

One question, didn't you need to register the timers too with libwww?
When I set up my X11 libwww interface in Amaya, I had to register them too,
using:

	   HTTimer_registerSetTimerCallback ();
	   HTTimer_registerDeleteTimerCallback ();

(Same principle as with HTEvent_setRegisterCallback).

You'll have to write your own HTInit.c module and link to it too. That's
what I did in Amaya to minimize the number of mini-libwww's that need to
be linked. Look at the tiny browser (Examples/tiny.c) for an example
of how to do it.

One last interesting question, why are you using libwww instead of ghttp?
