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.
