Complex exponentiation by real/complex 1.0 is not the identity.
GNU compiler & classic-flang perturbs the argument. Intel compiler does not. : https://godbolt.org/z/xTo9K1ceE
```
Program test_complex_expt
Complex :: x(3),y(3),xpt(3)
Real :: rpt(3)
x(:) = (1234.0, 2345.0)
xpt = [ 1, 2, 0]
y = x ** xpt
Print *,y(1)-x(1)
rpt = [ 1, 2, 0]
y = x ** rpt
Print *,y(1)-x(1)
End Program test_complex_expt
```
