From c23b5239ae0681624511e8bf98003f4c5bb9e0ff Mon Sep 17 00:00:00 2001

Subject: [PATCH] Remove the Py_FatalError() from initpyexpat(); the Guido has
 decreed that this is not appropriate.

Made somewhat more robust in the face of reload() (exception is not
rebuilt, etc.).

Made the exception a class exception.
