Hmm. I didn't quite understand that, and unfortunately svn.haxx.se is
unreachable from my home network right now. We can't just define the
object once in svn_iter.c, and then declare it "extern" in svn_iter.h?
Does MSVC have a problem with that? (I thought it was standard C89.)

Either one is fine, but having it be a real error object would be
better, of course.
