[C++] namespace alias bug

[Benjamin Kosnik]

On x86 linux, with current CVS g++:


    namespace Foo
    {
        enum FooEnum { Hi, Hello, HowAreYou };
    }

    namespace Foobar
    {
        using namespace Foo;
    }

    namespace FB = Foobar;

    void foobar(FB::FooEnum a_foo); 


This should compile. It doesn't....
