Your test case compiled fine when I tried it.

You didn't mention what version of gcc you are using, or what system
you are running it on.

non_lazy_ptr appears to be an Apple thing.  I don't know what it is
used for.

Mac OS X 10.5.2

It's just a guess, but I would try interchanging these lines:

template class Singleton<SingleClass>;

template <class Type> Type * Singleton<Type>::ptr;

That was it! I thought it would be a one-line fix and it turns out to  
be a no-line fix.

Thanks! This was keeping me from writing a more elegant solution.
