Python 2.3 will support source code encodings which rely on the
builtin codecs being available to the parser.

Remove struct dependency from codecs.py

   The final piece of this change...

   Strip down Setup.config.in and Setup.dist to the minimal sets required
       to get a working Python; setup.py will handle the rest

Setup, walks into Guido's East End nightclub with a tactical nuclear

exactly where it will do the most good, right in the middle of
configure.in.

With this patch, the set of libraries autoconfigured in is extended to

These are done as shared libraries by default, and so is bsddb -- that
seems to make the most sense.
