Summary: Access violation in call to CoInitializeSecurity

Initial Comment:
I'm using pywin32 build 202 and Python 2.3.4.  This call:

pythoncom.CoInitializeSecurity(None, None, None,
pythoncom.RPC_C_AUTHN_LEVEL_CONNECT,
pythoncom.RPC_C_IMP_LEVEL_IMPERSONATE, None,
0, None)

results in an access violation.  Tracing through the
call in a debugger, the problem is with the return from
pythoncom_CoInitializeSecurity: the stack has
apparently been corrupted so the function attempts to
return to a NULL address.  I believe the problem is in
the declaration of the mypfn function pointer. 
Shouldn't there be a some sort of stdcall or WINAPI
notation?  I think both caller and callee of mypfn are
popping the stack.
