--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
According to the standard in general a definition is also a declaration
([basic.def] p2 "A declaration is a definition unless it declares a function
without specifying the function’s body (8.4), [..]"), therefore [temp.explicit]
applies here as well.
I think that GCC is incorrect in not rejecting both cases, because the wording
clearly includes a "static data member of a class template" (This error still
exists in gcc 4.9 trunk).
I also think that the meaning of the code is well-defined only for C++11,
because in C++03 the concept of an explicit instantiation declaration did not
exist.
