[PATCH] Fix debuginfo for Fortran subref array pointers

At the time that subref array pointers were implemented, there was a
discussion on the list on how to do this.  Changing the ABI for array
descriptors was favoured but nobody had the time to carry out the
necessary surgery.  Therefore, I came up with the span kludge, which
arguably is worse than nothing:-(

If you have the time and the inclination, we would all be very pleased
if you could do it.  Otherwise, is there another volunteer out there?

Cheers
