Hi Jeffrey,
Hi Jean-Pierre,

you're right: I left my comments out.

I started all over, deleted both files and build a new file with just the 
three lines in it:

package Basic_Num_IO is
  procedure Num_IO;
end Basic_Num_IO;

The compiler error is now 

gcc-4.3 -c basic_num_io.ads
cannot generate code for file basic_num_io.ads (package spec)
to check package spec for errors, use -gnatc
gnatmake: "basic_num_io.ads" compilation error

I tried gcc-4.3 -c -gnatc basic_num_io.ads. No error occured.

How can I fix that?

Kind regards

George
