Note that libgdbm also implements the dbm_* functions. You can take a
program which uses the functions declared in ndbm.h and link it
against libgdbm. You don't have to modify it.

libdb also provides the dbm_* functions. However, it uses the libdb
(aka `Berkeley DB' or `NEWDB') file format. If you need to read files
which were created by libdbm or libgdbm, then you need to use one of
these libraries rather than libdb.
If you don't need to read existing dbm/gdbm files, then libdb's format
is better, as it is architecture-independent.
