Which is not completely true. See my previous messages about where cdotu
works correctly.

I am not completely sure about that it is ATLAS, only. It can be because
this Fortran function cdotu returns complex that is a struct object and
returning struct objects in C is very compiler dependent. It is well
defined for gcc compilers but many native compilers do not support such
things or require  different syntax when calling such a Fortran function
from C.

I have some ideas how to resolve this issue, I'll test them and get back
to you.
