Using DMD 0.97:

I have the following code in interface.d:

interface Map {
   bool equals(Object o);
   int size();
}

abstract class AbstractMap : Map {
   int size() { return 0;}
   abstract bool equals(Object o);
}

abstract class HashMap : AbstractMap {
   bool equals(Object o) { return true; }
}

and I get the following:

try adding a main. something like
 int main(){return 0;}
either that or compile with the -c flag.
