Enclosed is a patch file for Jim Fulton's Extension Class package that
makes it work with the new PyTypeObject structure in Python 1.5.2.
I've also included changes to ExtensionClass.h that make it work with
C++. The source that the patch is based on is the 1.2 release that
is available from http://www.digicool.com/releases/ExtensionClass/.

I'm very sorry, you must have started from a pretty old version of ExtensionClass.
Unfortunately, the information at: http://www.digicool.com/releases/ExtensionClass/
was sorely out of date. I just corrected this. The current version of ExtensionClass
is included in the Zope distribution, www.zope.org and works fine with Python 1.5.2.
