Thanks for finding that.  Please do file a bug in the tracker at
http://savannah.gnu.org/bugs/?group=gsl.  (A patch and test case would
also be handy!)

Looking at the source, there's an explicit check for 0^0 in
gsl_complex_pow but it is missing from gsl_complex_pow_real, so it
looks like a simple oversight.
