Without libstdc++ dependencies:

inline long double pil(long double x, int n) { return __builtin_powil(x, n); }
inline long double pl(long double x, long double n) { return __builtin_powl(x,
n); }

int main()
{
  __builtin_printf("pow(long double, int) :        %.21Le\n", pil(10.L,-4823));
  __builtin_printf("pow(long double, long double): %.21Le\n",
pl(10.L,-4823.L));
}
