Right, I fired too fast and just stumbled over this now, sorry. Here a short 
example:

#include <stdio.h>
int main() {
    _Complex double x =  2.5j + 1;
    _Complex double y = -2.5j + 1;
    printf("x = %f %fj\n", __real__ x, __imag__ x);
    printf("y = %f %fj\n", __real__ y, __imag__ y);
    _Complex double xy = x * y;
    printf("x * y = %f %fj\n", __real__ xy, __imag__ xy);
    _Complex double conj_x = ~x;
    printf("complex conjugation of x = %f %fj\n", __real__ conj_x, __imag__ 
conj_x);
}

Actually a quite nice extension.
