[Bug c++/15096] New: parse error with templates and pointer to const member

[wolfgang dot roehrl at de dot gi-de dot com]

We use the compiler to generate code for a PowerPc processor. 
Used invokation line for the C++ compiler:

ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig -mmultiple
      -mno-string -mstrict-align -O3 -fno-exceptions -fno-rtti
      -I<different include paths>
      -D<differen #define's>
      Z.CPP -oZ.O



// example program 1

template <typename T_>
class C1
{
public:
    C1 ();
    ~C1 ();
    const int C1<T_>::* getPtr () const;

private:
    int x;
    T_ y;
};


template <typename T_>
const int C1<T_>::* C1<T_>::getPtr () const
{ return &C1<T_>::x; }                      // <-- line 17


The compiler gives the following error message:
 
z.CPP:17: error: too few template parameter lists in declaration of `const int 
   C1<T_>::* C1<T_>::getPtr() const'


We get no error message if a typedef is introduced:

// example program 2

template <typename T_>
class C1
{
    typedef const int C1<T_>::* T_C1_INT_PTR;

public:
    C1 ();
    ~C1 ();
    T_C1_INT_PTR getPtr () const;

private:
    int x;
    T_ y;
};


template <typename T_>
typename C1<T_>::T_C1_INT_PTR C1<T_>::getPtr () const
{ return &C1<T_>::x; }

Confirmed, but can anybody test it with 2.95?

Retargeting to 3.4.1, being a regression on that release branch.
