I might be wrong, but my understanding is that the memory layout is not specified
in the standard. Can you point me to the section of the standard which specifies
the memory layout of a multidimensional array?
To me it seems as if you can only count on a specific memory layout if you
specify it to be the layout of a non-Ada languag, eg Fortran.
Strange indeed for a standard.
