Of course, the solution depends on your requirements.
If you just want *messages* in several languages, and accept to have
selection of the language at compile time, here is a useful trick:

declare all your messages as constants in packages, one package per
language, i.e.
package Messages_English is
  -- english constants here
end Messages_English;

package Messages_French is
  -- french constants here
end Messages_French;

Every module then declares:
with Messages;

And you simply declare a library level renaming:
with Messages_English;
package Messages renames Messages_English;

By simply changing "_English" to "_French" in the above two lines, all your
application will switch to French.

For an example of using this technique, see package Debug, available from
Adalog's components page (http://pro.wanadoo.fr/adalog/compo2.htm). Note
that this technique can be extended (to a certain extent) to manage inputs:
You declare the character that means "yes" ('y' or 'o'), etc.
