In reponse to Vaughn's query below.
1. When you declare you Bank_impl class you make reference to something called a POA_Bank. The compiler has no idea what a POA_Bank is so it indicates a syntax error. You will see that the POA_Bank class is actually declared in the Bank.h file which was generated by the idl compiler. Thus in order to implement a Bank_impl class you must '#include "Bank.h"' at the top of your file. This is why the idl compiler generated the file in the first place - so you can inherit from generated classes and hence ensure type safety.
2. The problem with Bank_impl.cc should go away when you solve the first problem.
A final suggestion. Do yourself a favour and add the --c++-impl flag to your IDL compiler flags. This will autogenerate a correctly structured Bank_impl.h and Bank_impl.cc file which you can then edit and flesh out with functionality.
