That's not true for C integer types (since at least 0.12 IIRC). They translate to multiplication code for x**N, N<=3, and to a loop for N>3. What type does 'x' have in your code? If it's a FP type, then the above is the correct way to do it (although a similar optimisation for constant exponents may be worth it). If it's an integer type, please double check the C code and provide a complete example.
