  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

  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
  with the SDK compiler.  This should fix the failing
  Lib\ctypes\test\test_as_parameter.py test.
........
  r58037 | georg.brandl | 2007-09-07 16:14:40 +0200 (Fri, 07 Sep 2007) | 2 lines
