Presumably because gsl is written in C.

I don’t think C has a complex type. In any case the C++ complex type 
seems to be difficult to make compatible with the gsl representation 
while maintaining the original code in C.

I realise it is possible to do some sort of conversion/casting in C++. 
But this is not likely efficient.
