Ok, you are right.
By reading again B. Stroustrup more carefully I now see that it was all there!
Thanks to you all and sorry to have wasted some of your time.

The ISO C++ Standard says all static data members referenced in a
program must be defined (outside the class body, as opposed to only
declared inside it), but they must omit the initializer if the
declaration already initializes it. Note, however, that no diagnostic
is required in case this rule is violated, which means the compiler is
allowed, but not required to, replace references to the static data
member with the constant used to initialize them.

Well, for static integral constant member it should work, accordind to
B.Stroustrup, 3rd Ed., pag 249, unless the standard has changed since then.
Indeed the "working.cc" example does compile .
