Oops, big glitch.  Charles had put a 1 in the column for argument list
type for all functions.  However many function call PyArg_Parse() and
need a 0.  This is so that when they didn't change anything, the can
do Py_INCREF(args); return args.  Reverted this back.  For atof(),
there's no reason not to use PyArg_ParseTuple(), so I changed the code
(atoi and atol already used that).
