>Description:
The problem occurs when two similar member functions (static or not) in a class are defined, the only difference being that one is templated and the other is not.  The code works fine if the definition of these member functions is put directly in the class definition.  But if these functions are defined outside the class body, gcc reports an error:

buggcc.cc:11: expected 2 levels of template parms for `static bool A<i>::foo()
   ', got 1
buggcc.cc:15: redefinition of `static bool A<i>::foo()'
buggcc.cc:11: `static bool A<i>::foo()' previously declared here
buggcc.cc:15: no `static bool A<i>::foo()' member function declared in class `
   A<i>'

Example:

template <int i>
class A
{
public:
   static bool foo();
   template <class J>
   static bool foo();
};

template <int i>
bool A<i>::foo() { return true; }

template <int i>
template <class J>
bool A<i>::foo() { return true; }
