[Python-Dev] anydbm test failures using Berkeley DB 4.2.52 on Solaris 8

[Skip Montanaro]

Trying to test some of my obsolete platform excisions on more than just Mac
OS X, I came across these test failures this evening on Solaris 8 when
Berkeley DB 4.2.52 was installed:

I don't recall seeing these before, but this is the first time I've built
from CVS on Solaris 8 w/ BDB 4.2.52.  The same tests work fine with Python
2.3.3+Berkeley DB 4.2.52 (Lib/test/test_anydbm.py is the same in 2.3.3 and
CVS).

I'm going to make a wild ass guess and say these aren't related to what I'm
doing.  Greg, have you seen this before?
