Testing & debugging?

[Tim Bray]

I'd be so much happier if I had unit tests, but it's tricky since  
everything's static.  My best idea is to have an #ifdef TESTING  
section in my code that has a main() in it that runs the tests (of  
course this means actually *understanding* the lovely makefile  
goodness I copied from Josh Rotenberg so I can produce a standalone  
runnable).  Anyone have a better idea?

Until I figure out the above, I'm going to be debugging more than one  
would really want.  Back when I was writing modules for Apache 1.* I  
got things wired up so I could debug in Emacs... that still about the  
state of the art?  -Tim
