I would have thought that, provided you choose the right orientation,
the rows would be as expected by C (ie contiguous values).
In
type M is array (Integer range <>, Integer range <>) of Float;
-- Column Row
the Row elements would be contiguous? (I can see there _might_ be
compiler differences, and ISTR that GNAT has a way of specifying
Fortran conventions).
(perhaps that should be "aliased Float")
