The following valid code snippet is rejected since at least gcc 2.95.3:
===================================
template<typename> struct A
{
template<int> struct B;
friend struct A::template B<0>;
};
===================================
The error message on mainline reads:
bugA.cc:4: error: expected identifier before ';' token
bugA.cc:4: error: friend declaration does not name a class or function
GCC also rejects
===================================
template<typename> struct A
{
template<int> struct B {};
A::template B<0> b;
};
===================================
with
bugB.cc:4: error: ISO C++ forbids declaration of 'B' with no type
bugB.cc:4: error: template-id 'B<0>' used as a declarator
bugB.cc:4: error: expected ';' before 'b'
Removing the redundant "template" keyword makes the code compile in both cases.
