It does indeed. The compiler invisible draws libraries in.

i.E.

raise Some_Exeption;

is mapped to

Ada.Exceptions.Raise_Exception (
    E       => Some_Exeption,
    Message => "");

As you can see the library give you the benefit of message. Why there is no

raise Some_Exeption with "Some Message";

I don't know.

But that is beside the point. As for Tasking: Look at Annex D to see the
libs used for Tasking.

Reduction? With GNAT: yes - use "-shared" and the base libs come out of a
DLL.

For beginners: Yes - you would have found a checkbox called "shared
library" ;-).

With Regards

Martin.
