friend from global namespace

[Roman Belenov]

In the following code fragment, gcc gives an error on the line with
comment:

2.cc:7: parse error before `('

Visual C++ 6.0 works Ok (and friend declaration works as intended).

Is it a gcc bug ? If not, how can I declare friend from global
namespace ?

------------------------------------------------------------------
class G {};
G f();

namespace N {
        G f();	
        class L {
                friend G ( ::f() ); /////
        };
};
------------------------------------------------------------------
