Summary: Patch for Lib/bsddb/__init__.py to work with modulefinder

Initial Comment:
The Python 2.4 Lib/bsddb/__init__.py contains this:

"""
# for backwards compatibility with python versions
older than 2.3, the
# iterator interface is dynamically defined and added
using a mixin
# class.  old python can't tokenize it due to the yield
keyword.
if sys.version >= '2.3':
    exec """
import UserDict
from weakref import ref
class _iter_mixin(UserDict.DictMixin):
...
"""

Because the imports are inside an exec, modulefinder
(e.g. when using bsddb with a py2exe built application)
does not realise that the imports are required.  (The
requirement can be manually specified, of course, if
you know that you need to do so).

There are two options for easy fixes for this:

  1. Move the imports outside the exec.  This wouldn't
effect the code at all, but would let modulefinder know
that they were there.

  2.  If 2.1 compatibility isn't required for the bsddb
module in Python 2.5, then the if and exec portion
could be completely removed.

Patches against today's anon CVS for each of these
options are attached.

Martin v. Löwis (on python-dev) indicated that Barry or Greg
Ward would be the appropriate person to decide which was the
correct option, so changing assignment to Barry.  Apologies
if is this not correct!
