And in a recent GNAT wavefront, it seems to only work for
one-dimensional arrays. Otherwise, you get an error "too few subscripts
in array reference" which doesn't make a lot of sense. This is 7.1w
from January, but supposedly 7.0 has full 2012 support. I've noticed a
lot of problems in this wavefront regarding 2012 support so hopefully
they're not issues in 7.0 stable.
