  Fix a crasher where Python code managed to infinitely recurse in C code without
  ever going back out to Python code in PyObject_Call().  Required introducing a
  static RuntimeError instance so that normalizing an exception there is no
  reliance on a recursive call that would put the exception system over the
  recursion check itself.

  Backport from py3k branch:

  Add a workaround for a strange bug on win64, when _ctypes is compiled

  Lib\ctypes\test\test_as_parameter.py test.
