Python 2.2a1 & Boost.Python

I am testing Boost.Python with Python 2.2a1.

Despite the pessimistic warnings at the end of
    http://www.python.org/2.2/descrintro.html
Boost.Python compiles without a warning (Linux gcc 2.95.2).

Some trivial fixes of the doctest tests were necessary.
These can be found in the boost_python_richcmp CVS branch.
When running the patched version of comprehensive.py,
one problem remains:

*****************************************************************
Failure in example:
class MISubclass2(RealPythonClass, Bar):
   def new_method(self):
       print 'MISubclass2.new_method()'
   bound_function = RealPythonClass().other_first
from line #157 of comprehensive
Exception raised:
Traceback (most recent call last):
  File "/net/cci/rwgk/boost/libs/python/test/doctest.py", line 490, 
in _run_exam
ples_inner
    exec compile(source, "<string>", "single") in globs
  File "<string>", line 1, in ?
TypeError: PyClass_New: base must be a class
*****************************************************************

When applying this additional patch...

diff -r1.8.2.1 comprehensive.py
158c158
<     >>> class MISubclass2(RealPythonClass, Bar):
---
>     >>> class MISubclass2(Bar, RealPythonClass):
comprehensive.py runs without a problem.
From comprehensive.py:
> We can even mulitply inherit from built-in Python classes,
> even if they are first in the list of bases
This does not seem to be the case with Python 2.2a1.
Is this an important problem?
