RE: from c.l.py, this should be biting us as well

[Laura Creighton, forwarding a msg from <[email protected]>]

There's a vigorous thread about this on c.l.py.  It's unclear what's wrong--
or indeed whether anything is wrong --since the test program's meaning isn't
defined by C:

> 	printf("fractional part = %f\ninteger part = %f\n",
> 					modf(x, &y), y);

The value of y isn't defined there (order of side effects isn't defined in
C).
