[Bug c++/21484] New: [g++] using typename doesn't work in case template : template inheritance
Is it just me or what?
===nested_defs.cpp===
templatetypename T
struct A
{
typedef T value_type;
};
templateclass T
struct B : AT
{
using typename AT::value_type;
value_type x;
};
int main()
{
Bint b;
b.x = 0;
return 0;
}

With Comeau C++ Intel 8.0 C++ it is ok.
---
By the way, if i want to access all members of AT inside B, without explicit
using, typedef,
etc, what can i do?
damn, if B is not template it works
===
templatetypename T
struct A
{
typedef T value_type;
};
struct B : Aint
{
value_type x;
};
===
if A is not template it also works:
===
struct A
{
typedef int value_type;
};
templatetypename T
struct B : A
{
value_type x;
};
===
only for template : template case it doesn't compile (g++, Comeau), although
intel C++ 8.0
works ok:
===
templatetypename T
struct A
{
typedef T value_type;
};
templatetypename T
struct B : AT
{
value_type x;
};
int main()
{
Bint b;
b.x = 0;
return 0;
}

Excuse me. The following is unconditionally offtopic, but
is there a way to use whole base namespace, say something like
templatetypename T
struct A { ... }
templatetypename T
struct B : AT
{
using AT::* ;
or
using AT::;
};
/none of these works, but i think the idea is clear/
