clhash.c does not compile in vs2022

[demoonj]

The following code will not compile with vs2022:

clhash.c

if(CLHASH_DEBUG) {
// avoid bad seeds
if (memcmp(&polyvalue[0], &zero128, 8) == 0)
polyvalue[0]++;
if (memcmp(&polyvalue[1], &zero128, 8) == 0)
polyvalue[1]++;
assert(memcmp(&rs64[1], &zero128, 8));
}

How can I avoid bad seeds while making changes?
