Seems to me Ada and C++ are the same here.  It's the different
terminology that's confusing.
In Ada, a "constant" object initialized by a user-defined function call
cannot be used in a "static"   expression.
In C++, a "const"    object initialized by a user-defined function call
cannot be used in a "constant" expression.
Same thing, different words.

C is different from both C++ and Ada in this area.
