Tue 04 May 2010 03:31:33 PM UTC, original submission:
gsl_complex_pow_real incorrectly returns that (0+0i)^0 = (0+0i). Based on the consistency with gsl_sf_pow_int and gsl_complex_pow, it should return (1+0i) for these inputs.

I extended the automatically generated test cases to include a number of pow_real tests.
