Interestingly G++ is happy to not instantiate the template when it's not
possible to, i.e. making this change and defining -DINCOMPLETE allows it to
compile:
template <typename T>
struct FussyTemplate
#ifndef INCOMPLETE
{
static_assert( test<T>::value, "not short" );
}
#endif
;
But if the class template definition is available it gets instantiated.
