Right, we're just starting C++ support in Clang, so it will be a while
before it is usable.

As Sebastian noted, the support for C++ function overloading is not
yet usable. We're missing user-defined conversions and reference
binding (semantic issues) and we don't have name mangling, so you
can't yet write a program that uses function overloading.

Regarding timelines, I can't say much. I expect we'll have most of the
remaining semantics of function overloading implemented within a
month, but name mangling (and other code-generation issues) are a bit
further off.
