--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Warnings during the first stage will not always be correct.


Anyways this has been fixed since r0-108388 which changes the code a lot and
removed the assignment.
So all fixed for GCC 4.7.0.

------- Comment #3 from jay dot krell at cornell dot edu  2010-08-22 08:56 -------
Best imho to put in the cast to quash the warning.
To be warning free -- esp. given how close you already are.
Sometimes I think warning-free across a range of compilers is untenable.
But you are in fact already very close.

Assigning -1 to an unsigned type is always safe.

------- Comment #1 from jay dot krell at cornell dot edu  2010-08-21 22:13 -------
clarification, where I assert what gives no warning, I was just testing with
like:

-bash-3.00$ cat 1.c
unsigned a = (unsigned)-1;
unsigned b = (0u - 1u);

I didn't yet test changing coverage.c.
