 Yes.

 Yes.  The relevant chapter and verse is 14.7.1/1
 
   [...] The implicit instantiation of a class template specialization
   causes the implicit instantiation of the declarations, but not of
   the definitions or default arguments, of the class member
   func-tions, member classes, static data members and member
   templates; and it causes the implicit instantiation of the
   definitions of member anonymous unions. [...]

 I meant "GCC-3.0.4 got it right but now we get it wrong".
