        type Foo_ptr is new Interfaces.C.Strings.chars_ptr;
>You can use `struct Foo *' without declaring `struct Foo'.
  That's like
    type Foo;
    type Foo_Pointer is access Foo;
except that in Ada you would need a full declaration of Foo eventually.
In any case, clearly if you don't know the structure of a Foo, but only
pass around pointers to them, then the suggestion
    type Foo_ptr is new  Interfaces.C.Strings.chars_ptr;
seems to fit.  Any problems with that?
