Mike,
Zdenek,

The attached patch fixes PR50322.

The test-case is supposed to succeed if the loop counter data-type has the same
size as a pointer. The patch defines TYPE to be an int datatype of the same size
as a pointer, and uses it. After this fix, there's no need for the avr xfails
anymore.

tested with avr, x86_64 and x86_64 -m32.

OK for trunk?

Thanks,
- Tom
