I'm going to assume that the word wrap between lines 1 and 2, 3 and 4
of this was unintentional.

These are hard errors for a reason.  They indicate bugs in your code.
A corrected version (with the unused arguments dropped for
readability) would be something like this:

#define DEFINE_MAKECARRAYITER(contType, memberType, getArrayFunction) \
  static iterator_range<memberType *> contType##_##getArrayFunction \
    (contType &c)

i.e. all you have to do is remove two incorrect and unnecessary ##
operators.
