- test5-execsymbols checks that a module can reach symbols that are defined in

the executable.  On linux you can.

+Can a module reference symbols in the executable?
+
+module1 exports module_name and operate(int,int).
+module2 exports n_operations and operation_occurred().
+
+uselib.cc uses symbols and functions from both modules.
+Module1 calls operation_occurred() in module2.
+
+Module2 calls register_module() in uselib.cc the first time
+it is called.
