I have looked at the GNAT2007 and Ada.Generic_Real_Arrays. It needs a
link to a BLAS/LAPACK library. I have tested it with compiled BLAS/
LAPACK with the gnat FORTRAN compiler. Some timing on Windows XP
(Intel Core 2CPU): to multiply two matrices of size 500 produced a
rate of 1.17 GFlops/sec.

Some questions
How do you use other blas/lapack for example Intel or atlas?
How do you increase the stack size (I would like to try 1000 by 1000
and I have 2GB of memory)?
