OK, I consider myself suitably educated/chastised. I now understand why
a version bump is such a big deal. Your objections are all reasonable, I
suppose I'm just used to living on the bleeding edge of everything.
Consequently I have changed the code to produce the same result in a
different way without using the new function. I've down-graded my
version to 2.6.26 and it all compiles cleanly. Please find attached my
revised patch, and thanks all for your advise.
