I get the same result on alphaev56-dec-osf4.0d (egcs-2.93.03) if I include
a main():

template<int N>
class A {
public:
  static const char * classname;
};

template<int N>
const char * A<N>::classname="Foo";

int main() {
  return A<3>::classname==0;
}

/scratch/local/bin/c++ bar.cpp
/usr/bin/ld:
Unresolved:
A<3>::classname  
collect2: ld returned 1 exit status
