The problem of complex functions is that they don't follow the C99
conventions at all. IN particular, they accept pointers instead of
values. I don't know whether the rational for using pointers is still
valid (it is mentioned that how to pass structure is compiler
dependent - I would guess this is true mainly for fortran, I would
expect the C ABI of every platform to fix those kind of issues ?)

Using C99 names for functions with different prototypes may be confusing,

cheers,
