                Well, it was intentional, if not very smart.

                The idea was that the config files essentially allowed workarounds for
platform deficiencies, so if your platform was conformant, you did not
need them. Including the config from the headers hides from the user his
platform's deficiencies, whereas he should be (painfully) aware of them
so as to complain to his vendor. Having to include the config files in
user code was supposed to raise awareness of the problem. Of course, for
the test files, they must be present.

                If this is found to be confusing or unwieldly, I can change.
