Sorry, I've messed it up. I meant "extern const" 
instead of "const" and thought
    extern const int X__fifty = 50;
could stand in multiple translation units and would be enough.


DWP 7.1.5.1 [dcl.type.cv], 2:

                                        ^--(#)

Does this mean that it _may_ _not_ be initialized 
if explicitly declared extern (like (*) sugggests)?

The DWP continues:
>   ... [can call default-ctor] otherwise if the const object is not 
>   initialized with an explicit initializer the program is ill-formed.

So does the "Unless explicitly declared extern" extend beyond
the semicolon (#) up to the definition of ill-formed ?
Then the wording is missleading, at least for my english skills.
Otherwise "extern const int i;" would be ill-formed.
