Addendum for those who continue to have difficulty:

I found that the order of the "template ..." vs. "template<> ..." made
a difference, but in linking, not in compiling.  From the previous example:
    template <> EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
    template <> EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;
    template  EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
    template EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;

The (equivalent of the) above would not generate symbols in my '.o', however:
    template  EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
    template EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;
    template <> EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
    template <> EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;
will work.   (Note: my case was slightly more complicated, in that instead of "EST_Regex" for the
final type, I had a templated type).  This was in 3.4.2.

Hope this helps.

Reduced to:
template<class K, class V> class EST_THash;
class EST_String
{
};
class EST_Regex
{
};
template<class K, class V>
class EST_THash {
private:
  static V Dummy_Value;
  static K Dummy_Key;
};
EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;

But this is invalid.  to explicit instantiation, do the follwoing:
template <> EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
template <> EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;
template  EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
template EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;

But just to define the space for the definition do:
template <> EST_Regex * EST_THash< EST_String, EST_Regex * >::Dummy_Value;
template <> EST_String EST_THash< EST_String, EST_Regex * >::Dummy_Key;
