[Zope] Re: Zope 2.8.4+Latest cygwin installation

[Jim Fulton]

I have no idea what the original symptom or situation was, so
I can't really comment.  I'll note, however, that the error
refered to in Pascal's reply results from a wart in Python's
type-definition protocols that I thought I had fixed, but maybe
I proposed fixing it and didn't get around to it. :(

More specific would be helpful. Is a custom C type involved here?
