Hi,
Attached is a patch to enable only if INT_MAX == 2147483647.
The h8300 port lets you select the size of int to be either 16 or 32
bits, so the following takes up only 8 bytes.
const vector unsigned int v1 = {10,11,12,13};
But the following memcmp compares 16 bytes of memory.
if (a != 1 || memcmp (&v, &v1, sizeof (v)) != 0)
abort ();
This results in abort().
OK to apply?
