Well, after some years, my basic understanding of complex analysis is not so
good anymore... branch cuts... discontinuity... many values... Riemann sheets...
What's that? ;)

But, I must say, my friend Maple9.03 gives the same numbers of submitter's mypow,
for the concerned cases, that is (0, 1), (-1.57*, -4.84*)...

So...
