Or better yet
#include <stdlib.h>
#include <stdio.h>

int
main ()
{
  char *end;
  const char *p = "6e-4966";
  long double l = strtold (p, &end);
  if (l != __LDBL_DENORM_MIN__ || end != p + 7)
    printf ("%Le %s\n", l, end);
  p = "1e-4965";
  l = strtold (p, &end);
  if (l != 2.0L * __LDBL_DENORM_MIN__ || end != p + 7)
    printf ("%Le %s\n", l, end);
  p = "2e-4965";
  l = strtold (p, &end);
  if (l != 3.0L * __LDBL_DENORM_MIN__ || end != p + 7)
    printf ("%Le %s\n", l, end);
  return 0;
}
so that we know if it is just the denorm_min() case or also other denormals.
