__builtin_cpow((0,0),(0,0))

[Ronny Peine]

Well, these were math lectures (Analysis 1,2 and 3, Function Theory, 
Numerical Mathematics and so on). In every lectures it was defined as 1 
and in most cases mathematical expressions are mostly tried to transform 
in equivalent calculations for the FPU (even though associativity is for 
example not preserved).

I don't know of any standard which defines this to 0.
