opps that should be foo3.adb in the command below (I copied the file content
to new file and named it foo3, but pasted the older command on the window which
was foo2.adb)

>> gnatmake -gnat2012 -I/lapada/ada  foo2.adb -largs -lblas

here is the command again:

>gnatmake -gnat2012 -I/lapada/ada  foo3.adb -largs -lblas
gcc -c -gnat2012 -I/lapada/ada foo3.adb
foo3.adb:10:13: expected type "Fortran_Real_Matrix" defined at labase.ads:94
foo3.adb:10:13: found type "Complex_Star_16" defined at labase.ads:52
gnatmake: "foo3.adb" compilation error

(I just did not want someone to get confused if they saw this).
