[C++] namespace alias bug

[Martin v. Loewis]

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

Thanks for your bug report. Here is a patch.

Regards,
Martin

// Build don't link:
namespace Foo
{
    enum FooEnum { Hi, Hello, HowAreYou };
}

namespace Foobar
{
    using namespace Foo;
}

namespace FB = Foobar;

void foobar(FB::FooEnum a_foo);
