Thanks, Jason, the above test case now works.
However, a similar problem with explicitly instantiated template classes still
exists.
Here is a test case.

struct test
{
};

template<
        typename T
>
struct template_test
{
        __attribute__((visibility("default")))
        void function();
};

template<
        typename T
>
void template_test<T>::function()
{
}

template
__attribute__((visibility("default")))
struct template_test<test>;

With gcc-4.7, template_test<test>::function gets hidden visibility, while with
gcc-4.6.2 it gets default visibility.
