This wouldn't handle the case when a clueless user has typed into
allegro.cfg:

   my_int=hello world

and you try to access it with

   al_get_int("my_int");

though. To be able to detect all such cases i think would require
either

   al_is_int(name);
   al_get_int(name, default_value);

or

   al_get_int(name, default_value, &error);

or

   al_get_int(name, default_value); /* which sets allegro_errno */

or of course

   al_get_int(name, &error);
   al_get_int_default(name, default_value);
