It used to use Interfaces.Fortran.BLAS, which was removed in GNAT GPL
2012/GCC 4.7. AdaCore reimplemented Ada.Numerics to improve portability
(to systems that don't have BLAS, LAPACK) at the expense of performance.
The body of Ada_Numerics.Generic_Arrays now says
with Interfaces.Fortran;
with System.Generic_Array_Operations;
and I think the latter is a GNAT unit? (of course, anyone could copy it;
it doesn't look unusual aside from a pragma Inline_Always).
Also, I don't have any other Ada 2005 compiler!
The library needs BLAS and LAPACK, easy enough on Mac OS X and Debian,
apparently a PITA on Windows.
