Define the derived structures

   You must define a structure for an entry in the hash table, and a
structure for the hash table itself.
   The first field in the structure for an entry in the hash table must
be of the type used for an entry in the hash table you are deriving
from.  If you are deriving from a basic hash table this is `struct
bfd_hash_entry', which is defined in `bfd.h'.  The first field in the
structure for the hash table itself must be of the type of the hash
table you are deriving from itself.  If you are deriving from a basic
hash table, this is `struct bfd_hash_table'.
   For example, the linker hash table defines `struct
bfd_link_hash_entry' (in `bfdlink.h').  The first field, `root', is of
type `struct bfd_hash_entry'.  Similarly, the first field in `struct
bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.
