Thanks, and sorry for the delay. Trying this out, I see (on amd64)
Checking to see how big your integers are...
try.c: In function ‘main’:
try.c:7:13: error: size of array ‘test’ is negative
static int test[1 - 2 * (sizeof(int) >= 1)];
^
try.c: In function ‘main’:
try.c:7:13: error: size of array ‘test’ is negative
static int test[1 - 2 * (sizeof(int) >= 2)];

try.c: In function ‘main’:
try.c:7:13: error: size of array ‘test’ is negative
static int test[1 - 2 * (sizeof(int) >= 4)];

I assume that's the expected error for too small size probes, and
a finished implementation would just redirect those to /dev/null ?
I'll forward this upstream, but please note that they're currently
frozen for a 5.22 release in May.
