I agree. I have to admit I wasn't really thinking about system headers
and things like that at the time.
I have one other question though: What happens when a header test fails?
Currently configure will fail completely. That's ok for kdelibs. But I
had the problem once that a missing header caused configure in an extragear
module to fail.
As the tests are now specified where they are needed it should be
possible to disable the affected directory and everything depending on
it. A warning is a prominent place would probably be a good idea.
