SF bug 533198: Complex power underflow raises exception.
Konrad was too kind. Not only did it raise an exception, the specific
exception it raised made no sense. These are old bugs in complex_pow()
and friends:
1. Raising 0 to a negative power isn't a range error, it's a domain
error, so changed c_pow() to set errno to EDOM in that case instead
of ERANGE.
2. Changed complex_pow() to:
A. Used the Py_ADJUST_ERANGE2 macro to try to clear errno of a spurious
ERANGE error due to underflow in the libm pow() called by c_pow().
B. Produced different exceptions depending on the errno value:
i) For errno==EDOM, raise ZeroDivisionError instead of ValueError.
This is for consistency with the non-complex cases 0.0**-2 and
0**-2 and 0L**-2.
ii) For errno==ERANGE, raise OverflowError.
Bugfix candidate.
