The correct source code is :


#define _GNU_SOURCE
#include <math.h>
#include <stdio.h>

int main()
{
long double X=0xd.96c3941c1094ed5p-7L;
long double C=cosl(X);
long double S=sinl(X);
long double C1, S1;
sincosl(X, &S1, &C1);
printf("diffC=%Le C1=%La C=%La\n", C1-C, C1, C);
printf("diffS=%Le S1=%La S=%La\n", S1-S, S1, S);
return 0;

}
