The problem is that Ada_Lapack is a conversion from Fortran to
Fortran-style Ada, and not a true native Ada implementation.
I wonder why Ada_Lapack needs convention-Fortran matrices, when it does
not use any Fortran code. Perhaps the reason is the frequent use in
Ada_Lapack of "for X'Address use Y", where X is an array. Yuck. But
writing a native Ada clone of LAPACK could be a lot of work, and might
need some deep understanding of how the Fortran LAPACK works.
