Duplicated symbol for function template declared as friend in class template

[gennaroprota]

Given the following code:

template< typename T >
class A
{
    template< typename U >
    friend void f( A< U > const & a );
};

//!     A befriended function template.
//!
//!     \param a An object.
template< typename T >
void
f( A< T > const & a );

MrDocs sees two fs (distinct SymbolIDs). The issue doesn't occur if we replace the function template with a class template. Also, it doesn't occur if A is a non-template class (although, in that case, MrDocs shows U as template parameter name, as if it got the friend declaration, rather than the global one, as "primary").
