gcc.c-torture/execute/builtins/pr23484-chk.c has on line 44:
if (snprintf (buf, l1 ? sizeof (buf) : 4, "%d", l1 + 65536) != 5
|| memcmp (buf, "655\0LLLL", 8))
but on a 16 bit platform like the avr, the "l1 + 65536" overflows and gives the
wrong result. Changing that to:
if (snprintf (buf, l1 ? sizeof (buf) : 4, "%d", l1 + 32760) != 5
|| memcmp (buf, "327\0LLLL", 8))
fixes the problem.
