Oh - and k3b is broken right now for me. I'll see if I can't figure out the 'scope' issue - I was good at that a year ago, but I seem to have CRS syndrome. (can't remember shi...)
How do I include preprocessor checks for libcdio > 0.83?? What is the syntax?
Take a gander at some of the libpng patches from a year ago.
I'm guessing you want to test the location of cdda.h in the configure scripts, not in the C++. Perhaps something like this:

Should the libcdio pkgconfig file reveal the location?
