Hi!

Can someone tell me, why this code doesn't compile?

//------------------------snip----------------------
namespace NspcA
{
namespace NspcB
{
template <class TempPar1, int TempPar2>
class TBeta;
} // of namespace NspcB

template <class TempPar1, int TempPar2>
class TAlpha
{
/* Line A: compiles
*/

//      friend class NspcB::TBeta<TempPar1,TempPar2>;
/* Line B: doesn't compile with error:
                                   parse error before `;' token
*/
        friend class ::NspcA::NspcB::TBeta<TempPar1,TempPar2>;
};
namespace NspcB
{
template <class TempPar1, int TempPar2>
class TBeta
{
};
} // of namespace NspcB
} // of namespace NspcA

int main()
{
        return 0;
}
//------------------------snip----------------------

When I uncomment line A and comment line B out it compiles perfectly.
Why does the way I address namespaces (absolute vs relative) influence
wether it compiles or not? Is it a compiler bug? If so: Is it known
and/or is there some way to fix it?

Compiler info:
GNU CPP version 3.0.3 (cpplib) (80386, BSD syntax)
GNU C++ version 3.0.3 (djgpp)

Thanks for any help in advance!

Bernd F.
