That's correct.  Both DW_AT_lower_bound and DW_AT_upper_bound express the
boundaries inclusively.  Array of length 0 must have DW_AT_upper_bound equal
to DW_AT_lower_bound minus one.

If you do not feel confortable with DW_AT_upper_bound that way you can also
use DW_AT_lower_bound and DW_AT_count with value 0.

That looks correct.

That should lead to a size of 0.

I am not sure where is a problem there but GDB handles non-pascal arrays of
length zero right AFAIK.
