Bernd,

this question should go to some C++ newsgroup, as it is only vaguely
related to boost.

You define members of a class template, which thus is a template declaration.
You are thus missing a template-parameter-list, just as the compiler tells you:

> boost::shared_ptr<test> SimpleSingleton<test>::as;
> boost::mutex SimpleSingleton<test>::inst_mutex;

should be:

template <> boost::shared_ptr<test> SimpleSingleton<test>::as;
template <> boost::mutex SimpleSingleton<test>::inst_mutex;
