  New Revision: 34703

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=34703

  Log:
    * ext/dbm/extconf.rb: weaken header/library consistency check if db is
      "ndbm".  It seems several (possibly historical) distributions
      provide libndbm.  However the content of libndbm vary: Berkeley DB,
      GDBM or even 4.3BSD NDBM.  (Mandriva, Tru64 UNIX, OpenSuSE,
      SCO OpenServer, ...)
      "ndbm" is not searched automatically now (dblib doesn't contain it)
      but configure --with-dbm-type=ndbm choose libndbm and ndbm.h.
