Thanks Stefan for your quick response. It seems I was a little off the mark :)
I had just ignored what I now understand to be some GCC magic for type sizes (as had my static analysis tool, which found the problem). Can anyone explain why the GCC instructions are used in place of the typical definition? Could it be expressed as: unsigned long __attribute__ ((__mode__ (__SI__))) with both the standard C part and the GCC part indicating the same size? (This would keep my static analysis tool happy).
