This just means the test shouldn’t be run on 32-bit Intel.

Can you run this:

#include <stdint.h>
#include <stdio.h>
#include "issignaling_fallback.h"

int main (void) {
  long double z;
 
  z = __builtin_nansl("");
  printf("%d\n", issignaling(z));

  z = __builtin_nanl("");
  printf("%d\n", issignaling(z));
}

compiled with -fsignaling-nans and the issignaling_fallback.h file from 
libgfortran?
