These are not languages for which the Ada RM defines Interface packages,
whihc make life easier and portable.(you have C, Cobol and Fortran). I guess
the best apporach is to check whether the Eiffel/Prolog implementations you
want to use have some C interface, and use that to connect to the Ada
program (via Interfaces.C).
Another apporach, these days, is to use a component architecture, like COM,
and then utilize something like GNATCOM, which allows you to interface to a
COM component from Ada.
(I thin that if you paln to target a JVM environment you may some more
options, but  I haven't really checked).

Maybe if you give more details someone would be able to give more specific
advice.
