- convert to using autoconf to help with portability issues, and redo the
  Makefile to take full advantage of it.

- global config file for rblcheck, that contains all known RBLalike
  DNS schemes. Will this invoke more overhead than this program should
  require, especially since the lists of sites will be static for the
  most part? Comments welcome.
