New C++ frontend bug since the big template change.

[Klaus-Georg Adams <Klaus-Georg dot Adams at chemie dot uni-karlsruhe dot de>]

The appended source doesn't compile any more:
friend1.C: In function `class mystream & operator >><int>(class mystream &, class a<int> &)':
friend1.C:23: member `amember' is a private member of class `a<int>'

egcs-2.91.47 didn't complain.

Note: If you leave out either the declaration of the specialization of
operator>> for int or the explicit instantiation of class a<int> the
program compiles.
