------- Comment #1 from rguenth at gcc dot gnu dot org 2006-12-14 11:21 -------
Even
_Complex double foo (double x)
{
return (_Complex double) x;
}
or
_Complex double foo (double x)
{
return x;
}
does not work. But
_Complex double foo (double x)
{
return x + 1.i;
}
does.

I believe there was a long thread about this for the C++ front-end.
The issue is that _Complex is a new fundamental type, ttherefore needs
elaboration about ordering conversion rules, including overload
resolution. The issue was coumponded by the fact that C++ has a class
template complex with slightly different rules.
I don't remember what the conclusion was.
