Bug in template declaration parsing

[Gabriel Dos Reis <Gabriel dot Dos-Reis at dptmaths dot ens-cachan dot fr>]

EGCS failed to correctly parse the following code taken from 
X3J16/97-0079 WG21/N1117:

template<class T> class task;
template<class T> task<T>* preempt(task<T>*);
template<class T> class task {
        // ...
    friend void next_time();
    friend void process(task<T>*);
    friend task<T>* preempt<T>(task<T>*);
    template<class C> friend int func(C);	// <== line 8
    
    friend class task<int>;
    template<class P> friend class frd;		// <== line 11
        // ...
};
