[Bug c++/34213] New: static member function in anonymous namespace can't be used as template argument

[tim at klingt dot org]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]

trying to use member functions of classes in the anonymous namespace as
template argument doesn't work.

the following code illustrates this issue:
template <void (*fn)(void)>
void call(void)
{
    fn();
}

namespace
{
struct bar
{
    static void fn(void) {}
};

}

int main()
{
    call<&bar::fn>();
}

it complains:
error: ‘<unnamed>::bar::fn’ is not a valid template argument for type
‘void (*)()’ because function ‘static void<unnamed>::bar::fn()’ has not
external linkage

Confirmed, another regression due to anonymous namespace changes.
